Hu Tao, Blazing Butterfly

Haste, Lifelink, Blazer - (At the beginning of each
combat phase you may sacrifice a creature. If you do,
Hu Tao gets +X/+X until end of turn, where X is
the toughness of the sacrificed creature.)

Whenever Hu Tao attacks, if a creature died during
this phase and/or the previous phase, you may draw
a card, create a treasure token and put a +1/+1
counter on another target creature you control.
