Odd Tier 20 Defense

I really don't know what to tell you. I'm just as confused.

Maybe they are just REALLY confident that the Ogma can handle anything green and red and decided three barsts would be the best answer to cover blue casters.

Probably a memetic nod to Ogma's recruitment chapter which, iirc, gave Ogma, Barst, Bord & Cord. I'm sure a few people surrender for meme teams, or he already got his 500+ Reinhardt / Brave Lyn / Dancer / etc score.

I'm only Tier 19...but after I net my first defense win high enough to secure 900 feathers I'll often switch to a dummy team to give someone a win and hopefully a laugh. That's probably what this is.
