It's very strong out of nowhere or when expected, it wins
I wouldn't be surprised if there's a game winning combo in this deck, but it probably doesn't involve Ravos, who provides recursion and access to White, but not a lot else
Were also not going to count serialized cards, since they are intentionally printed at a limited number and can skew the top end of the game to just a bunch of serialized cards, and thats not fun
It reads: At the beginning of your end step, if one or more creatures died this turn, you gain that much life and distribute that many +1/+1 counters among creatures you control. Basically, if youre playing a deck that kills things or sacrifices your own creatures, especially in token decks, you get a lot of life and can make your creatures stronger
I dunno, other than playing Bounce Lands, your deck looks fine
