What I mean with "politoed doesn't mind burns" is that outside of the damage that it takes, Politoed is not a physical attacker, and is not going to have it's attacks halved in power by burn. Especially if you have Aromatherapy/Heal Bell/Wish suport from things like Chansey, at least I have. Poisoning Politoed is much more effective if you want to win weather wars this way, as Politoed dies faster. Also, Keldeo is good as a Scarfer. I still use him with Choice Specs, however, as Thundurus-T is much more effective as a revenge killer, and under rain, Keldeo is more effective as a wallbreaker. Choice Scarf Keldeo only has the surprise value, that you can only have under rain (as the boost from Rain is equivalent to Choice Specs).
