Passage of Life

{t} add {w}{w}
At the beginning of combat on your turn you
may exile a creature card from your graveyard
If you do create a token copy of that card except
it Amass a Vigilance 2/2 Human Army it gains
haste until end of turn(They mutate into the
creature on top plus all abilities from under it)
At the beginning of your end step each opponent
loses life equal to the number of tapped creatures
you control.
