So I heard somewhere something about Mega Metagross using Stomping Tantrum instead of Equake because Tough Claws evens the power out, but is it really worth it, considering it doesn't quite add up and the double-power effect isn't triggered by protect?
Does anyone have a Snivy with Contrary (any nature/gender)? I have Vulpix (Snow Warning), Jolly Bagon with Dragon Dance, Torchic (Speed Boost) and Froakie (Protean).
