I've used it before, and I've always been frustrated because the mono aethers are almost impossible to get through with only the explosion and dischole combo because the discord only stalls for about 3 turns (there are a lot of pillars in mono aether) and that often isn't enough to win. Explosion gives only a one-turn window, and it's difficult to OTK them because RNG says your Lava Destroyer can never grow a third time.
