Give Them What They Want

If you spend {g} to cast this spell, create a food
token. If {u} was spend, a clue token. If {r} was spend, a blood token. If {w} was spend, a treasure token. If {b} was spend, a poison token
(it is an artifact with "{2}, {t}, sacrifice this token: target creature gets -1/-1 until end of turn").

Hey - they paid for it, so we'd better deliver.
