Who needs Grim?

High power is nice to have in the early game, but it is not necessary, and you shouldn't go out of your way to get it. In general, early game is not an area you need to be strong in. When faced with a wall of large SIGNI, most decks will play a few chump level 1 SIGNI to protect themselves (at level 2) and then play level 3 SIGNI bigger than Grim at (level 3). At this point, Grim's SIGNI body is just as good as Succu's. Level 1 and 2 SIGNI tend to be outscaled past level 3, which is why decks tend to run level 1/2 SIGNI with utility.

Texahammer and Enigma Aura's Life Burst are not worth considering, since the chances are small.

Nothing is worth that one guaranteed Life Cloth loss.
