Not a fan, personally. This is more of an overkill card. If you are not winning or cannot OTK with 3 HERO Fusions on board, then you most likely are doing something wrong. Or at least I cannot think of any scenario where you would want or need to Summon this without already being able to win.

I guess the card is fine, not exactly broken, but I imagine it would not be often played since Extra Deck space is too tight to run a situational boss like this, or perhaps as a side or meta call vs. deck that cannot deal with 3000+ ATK beaters immune to destruction.
