Notes & Combos

I was having a hard time against Maliss so I tried to think of a deck that could play 3 Lancea, 3 Chaos Huntress and 3 Fuwalos and have straightforward 1 card combos, so I came up with this mathmech build. The ratios might seem a bit weird but is what I ended up with after some tinkering. This was my easiest climb to M1 in months so I decided to share it here for the first time
