Notes & Combos
Pure Kash is kind of underrated imho. Because it can fit so many tech a lost coinflip doesn't equal a lost game, unlike many other decks. Going first is still preferred. Although the endboard is not that impressive, it is often enough to hinder your opponent so they can not kill you. On the offensive the deck is really strong, all four Kash on the field is lethal.
Most important card that is not inluded in all Kash lists is Swordsoul Supreme Sovereign - Chengying. All the banished cards make him an OTK machine and he is also important for clearing monsters like Avramax.
Flavour of the month choice is the Kaiju package with Small World. Borrelend Dragon and Purrely are prime targets.
