I would at least run 2x Vindicate in here MB. Other versions (including my own) run 4, but I can see why you would want to split with O-ring. On the other hand, vindicate likes to eat lands.
Also, Bitterblossom is a sweet card to have in here as a 2 of at least. Only a few things can take it out, and because of that your opponent has to race to kill off your tokens before getting swallowed up by them. I don't have any, but I occasionally borrow them from the shop when they let me. The deck is solid with or without them.
+1 from me. Great deck.
As to Bitterblossom
I would not change the main board to fit it in. This deck wins, and all to often we tinker with deck ideas that are proven to work. Bitterblossom
however is one of those rare cards in magic that are awesome all by themselves, Huntmaster of the Fells
is a good example. Would you consider running a 62 card mainboard?
