As of today, the Raichu mega evolutions abilities, got revealed. Mega y gets no guard
Because you forgot what no guard does basically you get 100% accuracy, but your opponent also gets 100% accuracy
And your figure yourself OK what’s so special about that? Well one move that it can get a zap Cannon, zap Cannon is a very powerful electric type but the downside is it’s 50% accurate but with no guard that 50 becomes a 100.
Mega Raichu Y it’s gonna be a beast!
