I tested this out a fair bit and I got mixed results. The thing is that Dialga can set up on half the stuff in Ubers especially on Support mons and Genesect too :D Most balanced / stall teams not having a strong physical attacker with a super effective move will be promptly set up on and crushed. However a major flaw of this et was the lack of recovery. Setting up a sub for a turn only to have it broken the next is INCREDIBLY wasteful for this Dialga. Yes, like poppy said on irc this is a niche set but it does have its uses. Leaning towards an approval.
