Ember the Volcano Buster

Haste, doublestrike,
When attacking create a tapped 3/3 elemental dragon token also attacking.
If damage is done to the opponent this turn, create an additonal 3/3 elemental
dragon token untaped.
Whenever a Elemental token is destroyed it deals 1 damage to target creature,
if a Dragon token is destroyed create a Treasure token
[the one that taps for any 1 mana].
