honestly I feel that a lot of these sets are gimmicky and have been posted just for the sake of doing something "different" while relying on nothing other than surprise factor (not saying that this is a bad thing, but the sets themselves should be effective in the first place). I may be wrong but honestly that's what it seems like to me :/ a lot of stuff here is underrated and would be pretty cool to build around, though, so here goes
CM Reuniclus
Mega Alakazam
Stallbreaker Togekiss
I feel like these three are pretty good and even though my nom follows the usual process of CCATs in set up mon+mons that lure/destroy its checks, idt there's anything /wrong/ with that
edit: just to clarify, i'm not saying they're objectively bad, just that they don't really serve the purpose of the CCAT imo. we need to create effective stuff and have a clear thought process, CCATs aren't solely for the purpose of doing something new.
