Isn't this that card that Aster used against Zane to defeat him in the anime? But he was burning Zane's LP, not himself, so did the anime fudge it on purpose. I got all excited when I first saw this card in the game before I read it's effect.
He milled HERO monsters, resulting in his Shining Phoenix Enforcer gaining ATK, overpowering Cyber End, as a result, Cyber End is destroyed in battle and Zane took damage from the battle, which is enough to deplete his remaining 600 LP.
There's monsters that increase their attack based on monster in your graveyard, also can help you summon monsters once they got to your graveyard, like using dragon's rebird, or red eyes spirit, the cons is you may lose huge life points if they are all traps and spell cards
