It’ll be a fun and highly annoying defense no doubt, but it’s a bit lacking in killing power since Frigg and Onyx would be your only hitters, with Bera doing her “death by a thousand minions” thing.
But hey what’s the point of this game if you don’t experiment a little and have some stupid fun sometimes right? I say go for it, see how it holds up, and report back the results if possible. I’ve certainly put out incredibly stupid defense before (like alternating R-G-B or pure yurple) just for the hell of it. Sure I end up losing more cups and revenges but hopefully my opponents appreciated the humor in it (most probably not, but oh well c’est la vie)
Btw I have Garnet Cobalt Onyx, and just pulled cKad from the most recent costume chamber. Once I get cKad to +18 in a few hours, maybe I too should try this annoying af defense just for the trollololol factor. Probably go something like Onyx-Garnet-cKad-Cobalt-cJoon/Roostley
