Elemental Hero Flameheat Gyros

[Sirce]

I can see a OTK with this >w<

[spoiler=Lore]"Elemental Hero Burstinatrix" + "Elemental Hero Heat"

This card cannot be Special Summoned except by Fusion Summon. This card gains 100 ATK for each "Elemental Hero" monsters in your Graveyard. When this card attacks, your opponent cannot activate a card effect that stops this attack. When this card destroys a monster by battle, both player send the top cards from their Deck to the Graveyard equal to the Level of the destroyed monster. If this card is the only monster you control, the original ATK of this card becomes 2800. Once per turn, you can reduce the ATK of this card and 1 face-up monster to 0. If you activated this effect, you can inflict damage to your opponent equal to the total ATK of both monsters.

Another good Elemental Hero fusion maybe you would want to make 1 that is a combination of Bladedge and Avian
