Trashman: It's a card with potentially limitless attack and defense. The discard loss isn't all that bad.
Requireing potentially limitless time to build up and limitless discard losses...To get +3 attack a player would have to sacrifice 3 cards over a period of 3 turns (making his intent bloody obvious to the opponent who will proceed to stop it.).
Compare it to other lvl 3 abilities:
Dark Hunter (3 ability points) - effectively a permanent +3 to attack, no negative effect.
Mustafae (3 ability points) - half damage from any attacker reflected back. no negative side effect.
Turey (3 ability points) - possesion of enemy card. Sacrifice Turey.
Tyrian (3 ability points) - enemy must show you his hand
So 3 turns and 3 discards just to get on pair with Dark Hunter?
Just doesn't sound right. If it was a lvl 2 abiltiy I'd say OK, but when I compare it with others. I trust you will think of something.
Maby making it add 1 Attack & Defense 8insted of OR), or a 2 point bonus..or change the ability altogether.. I dunno..
