{t}: You gain 1 life, or deal 1 damage to target
opponent.
Breeder: {3}{r}{w} (You may tap two creatures with
the same name that have breeder and pay their
breeder cost. If you do, a token that is an exact copy
of the creatures enters the battlefield tapped. You may
have twice as many creatures of a given name with
breeder in your deck as the format you are playing
would normally allow you to have.)
