Would there be any point to this strategy? I put together a Mega Aggron/Chansey team where Aggron could rest and then quickly be reawaken by Chansey with a penalty of only 1-2% of damage. (I picked Chansey because of her slightly smaller Atk stat compared to Blissey and because she's p.good with eviolite, but maybe a faster pokemon would be a better option.)

I admit that I'm a fan of interesting doubles gimmicks, but would there be any point to this? Surely it'd allow one to get off at least one safe rest?
