Seto, The Affluent Son

At the beginning of your end step, if you lost 2 or
more life this turn, create a treasure token.
({p/b} or {p/r} can be paid with either {b} or {r} or 2 life.)
Pay {p/b}: Sacrifice a creature, if that card shares a
card type with another creature on the battlefield,
target player sacrifices that creature.
Pay {p/r}: Discard a card, if that card shares a card
type with another permanent on the battlefield,
target player sacrifices that permanent.
