I think I might be missing the point of this deck. It just seems extremely slow for legacy with its current build.
There's no extra ramp, there's only 2 one-mana mana dorks, and big creatures with no evasion.
The first step I'd take is making it 60 cards and then lowering your landbase to 20 Forests- or even less- and throw in some more 1 drop creatures. (Preferably Arbor Elves and finish your playset of Llanowars). Might be worth it to invest in some
Inkmoth Nexus'es and focus on a Trample Infect route for a quicker/cleaner win.
The deck has some real potential here, but in a meta where you'll be facing turn 3 Emrakul's and Turn 2 Marit Lage or Turn 1/2
Ensnaring Bridge, having a bunch of creatures with base power and toughness being high while being a heavy mana sink is
dangerous.
It's a nifty deck idea, and I'm curious with how it'll play out.
