Half of your team is weak to bug with only blazekin's fire to stop it, with volcarona being very popular i think you'd have a hard time getting past it

zoroark gets flamethrower if im not mistaking

Thanks, I have blaze kick and Blast burn, My Zebstrika knows Flame Charge.

Replace Blast Burn with Stone Edge on blaziken, as you cannot afford the wasted turn, and over two turns, even flamethrower does more damage

Hydreigon should know Flamethrower or Fire Blast, just like every other one. Zoroark can learn it too, as you may already know.

Every Hydreigon has it, and Torment on a glass cannon like Hydreigon is not smart. And if you want a way to avoid some damage to Zoroark, put Mienshao at the back of the party, in case the opponent has psychic type moves
