friend just got a line of yveltals (ex and normal) and as far as i understood yveltal was a huge part of the metagame for quite some time. My question is it still being used even without dark patch? If so which variants apart from seismitoad stands out? And does yveltal have any sort of synergy with newer cards? I just want to get a better understanding of yveltal before i tell my friend uses quite a lot cash on the deck.
