Invinite Damage & Infinite mana

Alloy myr X2, Myr Galvanizer X2, Flameblast dragon

[Strategy master]

Alloy myr gives you mana of any color to your mana pool while myr Galvanizer if u pay one colorless mana and tap it makes it where all other myr's become untapped so with 2 Galvanizers u can do it over and over. But Flameblast dragon when it attacks u have the option to use his ability where u pay one mountain and X mana where X does dam too target player or creature.

Infinite combos are cool.
