Fabricate X, where X is the number of times this creature has been cast from your hand or the
command zone this game.
{1}{u/r}: Regenerate target creature. Activate this
ability only if you control an artifact.
When another creature you control dies, you
may pay {2} and sacrifice an artifact. If you do,
create a token that's a copy of it, except it's a
colorless artifact creature with Fabricate 1 and it
enters the battlefield tapped.
