*intents and purposes.
Anyways, it's still Guardians even not considering Lele. Drampa, Garbodor, Metagross, Ninetales, there are quite a few solid GXes in the set and the only super good GX out of SM base is basically dead due to Garbodor ruining FOGP item lock decks and will be even more dead at rotation since FOGP is going straight from standard legal to banned in expanded. Cards like Field Blower, Rescue Stretcher, and Choice Band became new staples overnight, I challenge you to find a good list that doesn't play them.
Honestly I think Guardians, in terms of how much it changed how the game is played, is probably the most impactful set since BW base. I mean almost immediately after the set released Shaymin fell off into the abyss, even before people were rotation speculating Shaymin lost basically half of its value. That's a strong symbol of how much this set has forced us to rethink how we play.
