Deathgrip

Q: Is the first friendly unit on Deathgrip a cost or a target? When do I kill it, and what happens if I don’t?

Deathgrip uses a nonstandard wording that we normally avoid, precisely because of these ambiguities. We’re issuing errata to bring it more in line with how other cards and abilities work. This errata establishes that 1) the friendly unit is a target, not a cost; 2) it is chosen along with the other friendly unit and killed as the spell resolves; 3) if you don’t actually kill it for any reason, either because it’s no longer a legal target or because you replaced its death with an effect like Zhonya’s Hourglass, you do not give the second friendly unit any Might. (You do still draw 1; we’ve introduced a paragraph break to make that clear.)

Card text now reads as:

[Reaction] (Play any time, even before spells and abilities resolve.)

Kill a friendly unit. If you do, give +[M] equal to its Might to another friendly unit this turn.

Draw 1.

Note: If the unit isn't killed, you won't inrease might of the other unit, but you would still draw 1.
