I have a suggestion. Build decks that you can actually afford instead of making proxys of all your "cards".

Actually, Treespeaker, Devoted Druid, and Ezuri dont make an infinite mana combo because regenerate does not remove the counters from the card, only combat damage.
Hey D, this is AB. If you're worried about having Stuffy Doll get tapped, you could put some Pemmin's Aura in your sideboard? It is a great blue enchant. It seems to me that this card fits in here perfectly. If you dont have your Orim's Chant out you can protect your Stuffy Doll with it. If you get attacked by a flying creature you can give the Doll Flying and then block with it, and initiate your loop that way, and you can just untap it aswell. It could also give you a chance to play multiplayer with Stuffy Doll. You could give it +1/-1 and kill it and then find a way to get it back out of your graveyard and then play it again and pick a new target after you have eliminated your first one.
I'm not sure if you realized this but with Tolsimir Wolfblood's activated ability he can only generate one Voja. If you use it twice the second legendary wolf token will kill both of them. I just wanted to point that out. Also if you want a wolf token deck I would suggest adding in a Wren's Run Packmaster.
