Father Gascoigne

Whenever Father Gascoigne attacks, you may
sacrifice a creature. When you do, it gets +2/+0
and gains first strike until end of turn and it must
be blocked by target creature this turn if able.
Whenever a creature that was dealt damage by
a creature you control this turn dies, exile it with
a bloodlust counter instead. Then transform
Father Gascoigne if there is three or more exiled
cards with bloodlust counters on them.
