A cool idea, but limited by the limiting number of dragon cards in the game and is still effectively a 2p card since most dragons are still 2p. Ultimately, another card that wouldn't see much play
I am sure that it would see a good amount of play.
In 3 DoD: pay 6 for a 15/15 flying unstoppable dragon that exhausts instead of dying and gives you card draw of two cards at the start of each turn.
In DoD, 2 FD: pay 5 for a 12/12 flying unstoppable dragon with flame strike 5 and immolates all cards in the opponents defense zone.
In DoD, 2 CoV: pay 5 for a 11/11 flying unstoppable dragon that spawns demons on death.
In DoD, 2 OoS: pay 5 for a 10/10 flying unstoppable dragon that heals you when attacking the opponents fortress.
and so on.
There are some strong options for the use of Miniature Dragon Avatar. So I am surprised that you thought it would not see much play if it was in the game.
Congrats to you TameRlane. Interested to see your challenge.
