Well my idea was the Mega Ampharos with Wish so I might as well add something regarding it.
I really like Wish on this pokemon because not only is it a cleric that can deal a lot of damage, but it now can also be a straight-up wall to many pokemon in OU. Here's some calcs with a few different OU pokemon using 252 Special Attack Modest M-Amph, not even fully invested in defenses:
252 SpA Mega Charizard Y Fire Blast vs. 252 HP / 0 SpD Mega Ampharos in Sun: 144-171 (37.5 - 44.5%)
0- Atk Mega Charizard Y Earthquake vs. 252 HP / 0 Def Mega Ampharos: 128-152 (33.3 - 39.5%)
252+ Atk Choice Band Talonflame Brave Bird vs. 252 HP / 0 Def Mega Ampharos: 113-133 (29.4 - 34.6%)
252 SpA Mega Manectric Hidden Power Ice vs. 252 HP / 0 SpD Mega Ampharos: 124-148 (32.2 - 38.5%)
Mega Ampharos can now switch in and wall all of these pokemon, as well as threatening them with some pretty heavy damage if they choose to stay in.
The problem with this is that Amph has to run WishTect to wall these pokes, as they'll 3HKO it before it can heal up. This would remove its chances of being a cleric, as both of its stabs have common immunities. Wish does improve it as a wall, but not so much as a cleric.
