No reliable phazers? There HAS to be a few things that learn Roar, Whirlwind, or Dragon Tail.
Pilowsine looks like the bulkiest Phazer in this tier, but here's a list of all the Pokemon that can learn phazing moves:
MC Pokemon capable of using Roar: Croconaw, Fraxure, Gabite, Herdier, Krokorok, Lairon, Loudred, Luxio, Pignite, Pilowswine, Quilava, Rhydon, Sealeo, Shelgon, Vigoroth, Zweilous
MC Pokemon capable of using Whirlwind: Golbat, Pidgeotto, Staravia
MC Pokemon capable of using Dragon Tail: Rhydon, Zweilous
MC Pokemon capable of using Circle Throw: Loudred
Lairon could also be used, with an immunity to Poison and decent Physical defence, but it has low Special Defense and 4X weaknesses to Fighting and Ground.
