>>45929082Mega Altaria is very interesting. She could be molded into a physical OR special attacker, the 50 bst increase basically forces you to choose one. Since Return doesn't exist in Gen 8 I would say special might be a little better. Draco Meteor, Fire Blast, Moonblast is part of her gen 8 learnset. Probably do those 3 attacking moves on a choice specs/life orb set, keep Natural Cure so she can use Rest as the 4th move. Stat distribution:
HP: 80
Attack: 70
Defense: 105
Special Attack: 100
Special Defense: 105
Speed: 80
This leaves you with great bulk and a special attack stat that when specs/orb boosted can be pretty tough to withstand very many attacks coming your way without any sort of special wall, and status is largely useless against her since she can swap out immediately, or Rest then swap out. This would be a very strong pokemon, probably similar to Zapdos right now being in OU with a lot of L.Orb + Roost sets going around. Some specs for wall breaking. She's definitely not as strong as zapdos in the sweeper department (Zapdos has 125 SpAtk and 100 speed), but she can stick around longer. Definitely ou or uu depending on how she ends up getting used and she has access to a few other notable moves (hurricane, roost, dragon dance, play rough).
Please post a nice image in return for my efforts.
