Thorim, the Unending Ember

If Thorim, the Unending Ember is played from your hand or destroyed, summon a 2/2 Red Flame Sprite token with "At each of your end steps, summon Thorim, the Unending Ember. This does not activate if Flame Sprite has summoning sickness"
"It didn't stop, the flames engulfed us all, so many dead, burnt to ash. Yet one man walked into it...with a smile on his face" - Witness to the Rebirth of Thorim
