Whenever you attack, you may sacrifice another creature or an artifact. If you do, create a 4/1 black Skeleton creature token with menace that's tapped and attacking. (It can't be blocked except by two or more creatures.) Choose a Background (You can have a Background as a second commander.)

({T}: Add {B}.)

Exalted (Whenever a creature you control attacks alone, that creature gets +1/+1 until end of turn.) {3}{B}: Regenerate this creature. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)

When this creature dies, you may put a -1/-1 counter on target creature.

Heroic — Whenever you cast a spell that targets this creature, create a 1/1 red Soldier creature token with haste. (It can attack and {T} as soon as it comes under your control.)
