Notes & Combos

Long have I waited for PEAK WATER.

I was just testing for builds when the Darew's 50 card list got me to master 2 with a 75% winrate. But after 3 quick loses Im back to M3. Tested Psych1c's 60 card build, I went 3-7 with 3 bricked hands in 10 games going down back to M4. I then adjusted the build to near 50-ish. Keeping Small World and Pank, removing TTT half on the climb back to master 2. After two close calls of deranking games, I went on a good streak to finally reach M1.

55% winrate. this might be the lowest winrate M1 deck I played, but it didn't feel that grindy to be honest. Darew's 50 card list got me to M2 with a 75% winrate though, so maybe that's a better version? Still, small world help a lot I cant imagine playing without it now.
