>>31148080>a card which reaches most of its value from the opponent overextending usually isn't a good card.Yeah, this is fairly accurate. Good players tend not to use cards unnecessarily and are likely to adjust their play to hinder their opponent if they can. That said though, Yveltal/Garbodor players often load up their Yveltal-EXs with energy as this actually powers up Yveltal-EX's attack.
