I'd just like to say that the 3 times I've faced the Truant/Befriend+Shandera combo I've been completely and utterly decimated by it.
Pokemon like Blissey, Burungeru, and Kyogre make excellent teammates for their ability to come in on the Fire-type attacks Aianto draws and because they are specially bulky.
The point, as I've stated, is to die right after using Befriend. Choice Scarf helps pull this off. Ex:
Aianto used Befriend!
Dragonite gained Truant!
Dragonite used Fire Blast!
Aianto Fainted!
(Shandera switches in)
Doesn't that seem like a waste of Pokemon spot on your team though?
The sprite isn't moving. What could Truant possibly have to offer?
Yup, the intelligent player will switch out 24 times until Befriend has no PP. =)
Once again, you CAN switch on the turn your pokemon would be loafing around. So if your opponent keeps switching while you befriend, they'll have no problem switching in and out on the turn you bring in Shandera. Shandera will most likely die if he's facing an opponent without truant if he's staying in.Also, how is it a waste of a pokemon slot if it enables the sweep of Shandera after +6 SpA, SpD and Spe?
