Just found this. Uhhh, Wizards, what's going on?
Goldspan Dragon (mythic) - 3RR
Creature-Dragon
Flying, Haste
Whenever Goldspan Dragon attacks or becomes the target of a spell, create a Treasure token.
Treasures you control have, Tap and sacrifice this artifact: add TWO mana of any one color.
4/4
I think I just found a new card for dragon tribal. Great attack trigger, value when removed, and seems rather strong. Even a 4/4 with flying and haste seems ok, and the extra just seems...extra. WOW
