Notes & Combos

K9 with the minimal subterror package, which provides stygokraken as a 5 and Guru + fiendess as needed grinding tools for an omni and a book effect.

Not better than just pure K9, but I wanted to have some fun with subterror again :)

Replays

Not many interesting games so I only saved one to showcase the subterror + K9 combo, standard k9 endboard with Guru for follow up.
