F.A. Overheat

If only your opponent controls a monster: Special Summon 1 "F.A." monster from your hand, and if you do, increase its Level by 3 until the end of this turn. If this card is in the GY and you control no cards in your Field Zone: You can banish this card from the GY; activate 1 "F.A." Field Spell directly from your hand or GY. You can only use this effect of "F.A. Overheat" once per turn.
