Notes & Combos

Very fun deck. I feel like a more Handtrap-focused approach would be better, especially next Banlist when Maliss gets hit. Breakers are strong, but if your opp draws 5 extra cards during their standard combo it is usually not enough to break everything.

Ultimate Slayer felt nice against Maliss and Ryzeal, but i also missed S:P in some games where both players are out of plays. Reboot feels very strong.
