Devil’s Advocate here. 4x Grave Mistake seems a little gutsy coming from a player who claims “zombies are better” this meta, playing a deck with a high curve. Some decks (i.e. many Valk builds) run zero gravestones for your bouncing pleasure... I just wonder why Lil Buddies are not your choice when you’re looking for synergy with Briar Rose.
Point #2: “this deck has a high win rate” and “zombies are better” sounds like a contradiction. From my perspective zombies ARE better... but that’s because I play zombies and my deck has a decent win rate. Then again, I played an accidental ranked game with one of my middling plant decks and won it, so I guess I have a 100% win rate with plants.
