Not sold on Toucannon or sure what he functions as. AB removes Roost and Featherdance potential, so I guess you're not losing much (depending on how you play). Again, he's slow, so he's gonna take hits.
You need someone faster to poke holes and Garchomp can probably so that while providing you electric immunity, fire resistance, ground offense, and occupy the Mega slot.
Or ditch the Toucan for Salamence for your mega slot, and you can brainstorm for a good regular last slot fit. Thinking water/ground
