Most potent Legendary?

that really depends though if we’re talking lore mew is technically more powerful since mewtwo lacks the power to transform into any pokemon even though both have really high bst mew isn’t aloud in competitive since it’s a mythical that can build its moveset any way it desires with tm’s plus mewtwo really doesn’t get competitive play even when it’s aloud with people opting to choose legendaries like zacian xerneas and ogrepon over it in the tcg mew vmax was a top deck until it was rotated out the few instances i think that mewtwo is better than mew is in unite where mewtwo was a terror on launch and mew is from the last time I’ve played kind of a niche pick also tcg pocket mewtwo ex gardevoir is top meta right now and the only card of mew which you get for getting the kanto dex complete acts like a hand scope which is kind of a weak card sorry if I sounded rude or counterintuitive I more so just like reasoning to back up claims please don’t let this rub off on you the wrong way
