Getsuga Tensho — If one or more Hollow, Soul or Human creatures you control attacks your opponents, those opponents exile cards from the top of their library until they exile a nonland permanent. Those opponents lose life equal to the mana value of that spell. You may then cast that spell at any time by paying life equal to the mana value.
All creatures you control gain +1/+1 for each Hollow, Soul or Human creature you control.
