Notes & Combos

Reached Master 1 on 13 February 2026.

Overall climb was pretty smooth up until M2 where I went back and forth a couple of times until I finallt reached M1.

VSK9 and Mitsurugi Yummy remain as the hardest matchups due to the multiple disruptions they can put out during anyone's turn.

Against VSK9, I started to take notes on what cards my opponents revealed on their hand. It made monitoring their hand easier. Not necessarily made the game easier, but at least I can identify what disruptions they have on hand.

Don't hesitate to fire off your Purulias before your main phase.
