>>21828517The closest thing to a reliable defensive check outside of Ubers is specially bulky Umbreon, who can Wish/Protect Focus Blast if it doesn't take one coming in, and reliably 2ko with Foul Play.
>>21828887The main challenge here is that even in Ubers, Unbound Hoopa is pretty slow. It will probably be a good stallbreaker, and it has enough special bulk to fend off and beat established special attackers.
