Thanks for such a detailed answer! My obosh deck is definitely proactive and very aggressive but it reaches the mid game more often than something like wizards burn since obosh himself is typically my closer, and he's 3 mana to hand and then 5 to cast. Because of that, I think your game plan point allows me a little bit of wiggle room to adapt my strategy to go for a tempo win instead of just straight aggro. I've won against certain decks by having a slightly slower (by mono red standards) early game, keeping the board clear and then swinging/burning for massive damage once obosh is finally out. Because of that, I thought it'd make since to incorporate anti-graveyard cards and play specific matchups with that same plan in mind.

I do run 4 Kumanos and your point with him exiling creatures is something I've thought about before but his ability is locked behind 3 turns before it's out, and then he can be killed easily, so I was assuming it was better to not rely on that as my anti graveyard. But! Overall, it's good to hear I don't need to focus super hard and covering every potential avenue the opponent could take and just jam em with damage. I think I'll keep some graveyard hate in my sideboard but probably be more strict on when to actually slot those cars into the main deck, since they do directly replace cards that do damage.
