Because of this battle, I have a suggestion.
In a Doubles battle, when Protect is shifted to an ally, it should count as a protective move used by that ally. (Meaning the ally should not be able to immediately Protect/Detect/Evasive Agility/Evasive Teleport/Dodge the action afterward)
Otherwise, you get ridiculous Perish Song run-out-the-clock battles, like the aforementioned one.
When one player hasn't got a prayer of winning, no matter what they do, something is seriously wrong.
EDIT: @Lou, Fang does know Roar. He's also Taunted. Not too much help, that.
So, as it turns out, Volt Switch and U-Turn remove enemy-inflicted Perish Song, which is a perfectly logical way to solve the aforementioned problem.
So ignore this post...
