The Red Pool

Whenever a nontoken creature an opponent
control's dies, put a blood counter on The Red
Pool.
{t}: Add one {r} for each blood counter on The
Red Pool.
{2}{r}{r},{t}: Reveal the top card of your library. If
it's a creature card, put it onto the battlefield. Otherwise, put it into your graveyard. That
creature has Haste and is a red Horror in addition
to its other types.
