Notes & Combos

Yeah, I'm morphing into the CrystronK9 supergoat. I was getting my **** kicked to around 1400 and then I just had to dig deep and remember who the **** I am. These folks hate to get their spells CANCELLED, but I love it. This is one of the best decks, even if there are other turnskip decks this one has handtrap resilience so it makes for better climbs.

My ID IS 055-267-853 FOLLOW ME, I have some replays, and if you leave a comment I will do my best to give you a genuine answer. I don't gatekeep + I want to move on from CrystronK9 soon I think i'm at 98% with this variant.
