Red and Black Legac [Unknown Event]

If you spent black mana on this creature, it enters with a deathtouch counter. If you spent red mana on this creature, it enters with a first strike counter. If you spent both, you choose which one counter it enters with.

At the beginning of your upkeep, flip a coin. If it’s heads and this creature has deathtouch, or if it’s tails and this creature has haste, create a treasure token.
