Echoing Boon

Echoing Boon rulings:

2016-08-23: You must name a Magic card. Notably, you can't name a token.

2016-08-23: If you play multiple games after the draft, you can name a different card in each new game.

2016-08-23: If an alternative cost was paid for the spell being copied, such as a madness cost or surge cost, the same alternative cost is considered to have been paid for the copy.

2016-08-23: The instant or sorcery spell can target other things as well, as long as one of its targets is a creature you control with the chosen name.

2016-08-23: When Echoing Boon's ability resolves, it creates a copy of the instant or sorcery spell. The copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger. The copy will then resolve like a normal spell, before the original spell resolves but after players get a chance to cast spells and activate abilities.

2016-08-23: The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If you can't choose a new legal target for one of the targets, then it remains unchanged (even if the current target is illegal).

2016-08-23: If the spell being copied is modal (that is, it says "Choose one —" or the like), the copy will have the same mode. You can't choose a different one.

2016-08-23: If the spell being copied has an X whose value was determined as it was cast (like Subterranean Tremors has), the copy will have the same value of X.

2016-08-23: If the spell being copied has damage divided as it was cast, the division can't be changed (although the targets receiving that damage still can).

2016-08-23: Conspiracies are never put into your deck. Instead, you put any number of conspiracies from your card pool into the command zone as the game begins. These conspiracies are face up unless they have hidden agenda, in which case they begin the game face down.

2016-08-23: A conspiracy doesn't count as a card in your deck for purposes of meeting minimum deck size requirements. (In most drafts, the minimum deck size is 40 cards.)

2016-08-23: You don't have to play with any conspiracy you draft. However, you have only one opportunity to put conspiracies into the command zone, as the game begins. You can't put conspiracies into the command zone after this point.

2016-08-23: You can look at any player's face-up conspiracies at any time. You'll also know how many face-down conspiracies a player has in the command zone, although you won't know what they are.

2016-08-23: A conspiracy's static and triggered abilities function as long as that conspiracy is face-up in the command zone.

2016-08-23: Conspiracies are colorless, have no mana cost, and can't be cast as spells.

2016-08-23: Conspiracies aren't legal for any sanctioned Constructed format, but may be included in other Limited formats, such as Cube Draft.

2016-08-23: You name the card as the game begins, as you put the conspiracy into the command zone, not as you turn the face-down conspiracy face up.

2016-08-23: There are several ways to secretly name a card, including writing the name on a piece of paper that's kept with the face-down conspiracy. If you have multiple face-down conspiracies, you may name a different card for each one. It's important that each named card is clearly associated with only one of the conspiracies.

2016-08-23: As a special action, you may turn a face-down conspiracy face up. You may do so any time you have priority. This action doesn't use the stack and can't be responded to. Once face up, the named card is revealed and the conspiracy's abilities will affect the game.

2016-08-23: At the end of the game, you must reveal any face-down conspiracies you own in the command zone to all players.

2016-08-23: A conspiracy with hidden agenda that has a triggered ability must be face up before that ability's trigger condition is met in order for it to trigger. Turning it face up afterward won't have any effect.

2016-08-23: At the end of the game, you must reveal any face-down conspiracies you own in the command zone to all players. Notably, you can't bluff conspiracies with hidden agenda by putting other cards into the command zone face down as the game starts.
