1 Tuner + 1 or more non-Tuner FIRE monsters
If you control a face-up Continuous Spell/Trap Card, this card cannot be destroyed by battle. Once per turn, during either player's turn, if your opponent would Special Summon a monster from the Extra Deck: You can banish 1 FIRE monster from your Graveyard; negate the Summon, banish it, also inflict damage to your opponent equal to its Level/Rank x300. (If that target has a negative Level, treat it as having a positive one for this effect.) Once per turn, during either player's turn: 1 Xyz Monster you control does not have to detach Xyz Material to use its effect, but if you use this effect, this card cannot attack during your current or next Battle Phase.
