Super poly will be too op. Doesn't even matter if we have a bad selection pf fusions. What makes it threatening is it's unresponsive monster removal. Very dangerous card and should only be released with a single copy in Duel Links and nothing more
The same could be said about Lava Golem and the new powerful cards of the EX decks like Neos and Red-Eyes Fusion, or even AG Reactor Dragon, but here we are. Multiple copies of Super Poly will be available, if you are willing to pay for them.
