I'm gonna buff all 3 birds. First, for all 3, give them a 20 point bst boost. Zapdos goes to 110 HP, Moltres to 110 Speed, and Articuno to 105 Speed.
Next, swap Articuno's SpA and Def.
Then, Give them Weather Abilities as HAs. Now Articuno can set Aurora Veil reliably, Moltres can spam high power Fire Blast and Solar Beam, and Zapdos can use Thunder and Hurricane well.
Finally, lets boost their movepool. Zapdos now gets Hurricane and Weather Ball, Moltres gets Fiery Dance and Giga Drain, and Articuno gets Air Slash and Aqua Ring.
