If we get instant fusion and the extra deck becomes larger (at least 10 cards), maybe this level 4 water could be useful. And 1000 lp can trigger somes skills too.
3(4)x Monster cards
-5(6) to make this 1500 beater and that's IF you draw the cards you need. Possibly the worst card in the game, like even Gate Guardian has its uses, even as something to discard. This monster just sits in the extra deck and does nothing.
