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