Nitro Warrior

Synchro (You may sacrifice a Tuner creature and
another creature who shares a color with this spell,
where the total mana value is greater then or equal
to this spell's, rather then pay this spell's mana cost.)
Whenever you cast a noncreature spell, Nitro
Warrior gets +2/+0 until end of turn.
Whenever a creature dealt damage by Nitro
Warrior this turn dies, you may have it fight
target creature that opponent controls.
