General Rulings For Exodus:
- You don't pay a cost until the card triggers or begins resolving;
- This means you can nullify or cancel out a symmetry or Ability that has a cost by playing cards in response that destroy their energy source;
- i.e. If your opponent plays Vortex and they only have 1 energy on their field (which they are going to use to pay the cost), and you play a Cataclysm in response and destroy that energy, their Vortex will go straight to the graveyard without happening since there would be no energy to pay the cost.
- Likewise, if your opponent plays Unsummon on your only creature on the field, you may stack/play Reversion on your own creature to send it back to your hand. The opponent's Unsummon would then have no available targets and go straight to the graveyard without happening, and your opponent would not have to pay its cost.
- When a symmetry card or effect is played in response to your symmetry card, the card played most recently (card on top of the stack) happens first. Then, any remaining cards that must resolve experience Playback and may change targets if the owner chooses.
- Playback also happens when a creature is attacking and some other card effect causes a target to change or the state of the field to change. In this instance, Playback takes place and the attacking creature may change targets or stop attacking all together!
Instants and the Draw Phase
- Once your begin drawing during your Draw Phase, each player cannot play symmetry cards until you finish drawing because a player draws simultaneously from their Main Deck and Energy Deck;
- i.e. You can't play Forest of Crags during your Draw Phase if that's the first card you drew before drawing 2 more from the Main Deck;
- i.e. You can't play Vortex in the middle of your opponent's Draw Phase after they draw Main Deck cards, but before they draw Energy cards or Vice Versa;
- If a card says, "Each player," it affects every player in the game (even in multiplayer), but if a card says, "your opponent," you choose the opponent to affect;
- When a creature is summoned and it has a "When this creature is summoned..." Ability, the opponent can play symmetry cards in response to the summon, thereby stacking over the summoned creature's Ability;
- Symmetry cards are instant-speed, while creature Abilities are not. However, a symmetry cannot be played in the middle of a creature's Ability as it is resolving;
- i.e. If a Rare creature is summoned on a pile of 1 energy and the opponent uses a symmetry card in response to destroy that single energy, the creature would be immediately destroyed and its effect would not happen because it would not have any energy left before its Ability would trigger.
Field Tracking (What is Considered to be 'In-Play'?)
- The field only tracks what is "in-play". Cards in your hand, Main Deck, Energy Deck, and graveyard are NOT considered to be in-play;
- If under any circumstance a creature re-enters play due to an effect or otherwise, it "registers" as a new creature on the field and is able to attack again (even if it already attacked during that same turn before leaving play);
■ While this creature is on the field, it is unaffected by all symmetry cards (both yours and your opponent's).
■ It is even unaffected by symmetry cards that don't target it, such as Cataclysm, or symmetry cards that affect every creature on the field in general;
■ If your opponent plays Cataclysm or Leech, targeting an energy attached to Lantern Leaflore, they may, "Select one energy from a creature or pile...", but since the energy attached to Leaflore is considered "from a creature", it can't be affected and therefore would not lose energy.
■ When a symmetry card requires you to pay its cost, you cannot pay the cost from Lantern Leaflore. This is due to the fact that you must pay a cost from "a creature or pile" and this particular creature cannot be affected by any symmetry cards.
■ When this creature attacks, it must always use its Ability--Transcendent Force.
■ When declaring an attack using Ethereal Aurorialis, your opponent must choose to play or not play any cards in response before the top card of the deck is revealed;
■ By the time its Ability has triggered, it is too late for your opponent to activate any symmetry cards in response until after damage has been dealt.
Cosmic Shield Archangel
■ When this creature is summoned, its Ability must trigger unless it is removed from the field in response to being summoned.
■ You do not pay the energy cost for its Ability until it triggers;
■ Its effect says that players must only send a Rare creature from their field to the graveyard (attached energy remains in play);
■ If Archangel is summoned on a pile of 1 energy and you pay the cost from itself, the Ability is in the middle of resolving, so both players must send a Rare on the field to their graveyard. However, Archangel has no energy left and is immediately sent to the graveyard. In this case, it does not count as your Rare and you must select another Rare creature on your field to send to the graveyard if one is available.
■ When this card is played, both players can still stack symmetry cards in response before discarding their hand.
■ Cards played in response to Vortex happen first;
■ If Vortex is played in response to a Vortex, players can continue playing symmetry by "adding to the stack" after the first Vortex has resolved because symmetry are all instant-speed;
■ Vortex can be played at the start or end of a player's Draw Phase, but not in the middle while they are still drawing;
■ What You Can't Do: You can't play a symmetry while another symmetry is resolving;
e.g. You can't play Forest of Crags if you drew it from a Vortex and have only drawn 2 of the 3 cards from Vortex.
■ Leech is an all-or-nothing type of card;
■ Because its effect is broken up into 2 sentences, the first effect can't happen unless the second is possible and vice-versa;
■ Leech cannot be used to start a new pile of energy; it must be added to an existing one;
■ Leech can be played in response to a "When this creature is summoned..." Ability and will stop the Ability if it destroys the creature's last energy;
Victory, Keeper of the Order
■ Victory's Ability--Royal Decree makes all of your other Order creatures (besides herself) unable to be attacked by your opponent while she is on the field;
■ If you have 2 Victory, Keeper of the Order on the field, your opponent cannot attack either one because of each affecting the other;
■ If you have 2 Victory, Keeper of the Order on the field, your opponent must destroy or remove a Victory, Keeper of the Order by other means (symmetry or creature Abilities) before they can attack your creatures;
■ You do not need to have another card in your hand to discard in order to play Cloudburst Spiral;
Glimpse of the Sanctuary
■ Because both parts of this card's effect involve the word, "may", you do not have to add an energy to a blank pile in order to draw a card from your Main Deck;
■ Your opponent can add an energy to one of their blank piles either way, as long as they have blank pile(s) of energy on their field;
■ After you attack with creature A, then play Apparition Grove to switch creature A with creature B in your hand, creature B may attack since it is a new creature even though it is using the same pile of energy;
■ i.e. If your Princess of Blades attacks, then you use Apparition Grove to switch it with a Legendary Blade Luhzarus in your hand, Luhzarus may attack immediately. Then, you could also Pay 1 energy to trigger its Ability: Blade Barrage and have Luhzarus attack yet again;
■ Apparition Grove can be used on a Legendary Blade Luhzarus on your field to switch it with a second Legendary Blade Luhzarus in your hand to effectively attack 4 times per turn with the same pile of energy OR up to 6 times per turn if you have 2x Apparition Grove;
■ Chains affects the player and does not target the creatures themselves;
■ i.e. Even if a player is 'chained', he or she still cannot attack with a Lantern Leaflore (even though Leaflore is unaffected by symmetry cards) because the player is unable to command the creature to execute the attack;
■ Crystallize cannot target or affect Lantern Leaflore;
■ On-summon creature Abilities (i.e. "When this creature is summoned...") can be negated by this card; after the end of the turn, the creature will already have been summoned and its on-summon Ability will not trigger if this card was played in response to the summon;
■ Energy cannot be placed on top of the Main Deck with this effect;
■ Energy cards can't enter the Main Deck, so only a creature or symmetry card can be chosen by this card's effect;
Carcery the Chemical Oddity
■ When this creature enters play (whether by summon, symmetry effect, switch effect, etc.), its Ability triggers immediately, but symmetry cards can be played in response to its Ability before it begins resolving;
■ You must have at least 1 of all three Rarities (Common, Uncommon, Rare) on your field in order to blow up their energy and cause direct damage to your opponent's Life Points;
■ If you do not meet all of the conditions (i.e. missing only 1 Rarity), you lose 2 Life Points when this creature enters play;
■ You cannot use its energy-destruction effect if you do not meet all of the Ability's requirements;
■ The Energy Heartpulse Ability is an all-or-nothing effect: you can't pick and choose how many energy from each creature to explode for the effect;
■ If you have more than 1 creature of a certain Rarity in play when this Ability triggers, you may choose which of your creatures to use as part of this Ability's effect;
■ Due to the wording, you cannot choose multiple creatures of the same Rarity for this effect, it must be exactly one of each Rarity;
■ Carcery the Chemical Oddity can choose itself to meet the Rare requirement as part of its Ability since it is a 3-star Rare and it is counted as being 'in play' when it hits the table;
