I know that there's gonna be people like "wow, what a scrub playing Arena, you can't even play lgs-custom-variant-historic-commander-boogaloo" but honestly? I made this deck basically for free and have been consistently winning for several hours now. In real life I built a basic deck that cost me almost $50 and I used it maybe five times, and now it's not legal in standard because I didn't pay another $50 to get the same cards with a different icon.
Anyway Purrgatory is a cat-focused deck with Kaheera the Orphanguard as companion. It features such hilarious game mechanics as "oops all of my dead creatures are back on the field with higher stats" and "good luck killing me, I regenerate health constantly every turn, and that makes my creatures stronger!"
