I think Door of Destinies is a bit slow most of the time, but it seems to work on this deck! I'd definitely not run Coat of Arms, though. It's just way too good for your opponent most of the time.

One thing that might be nice, given how much the deck likes having forests in play, would be maybe switching out Llanowar Elves for something along the lines of Elvish Pioneer or Skyshroud Ranger? Though you'd probably need to run more lands to get the most out of them, since they're useless if you don't already have a land in hand. But they're nice in that you still have the extra mana even if they get removed, on top of helping out with Scute Mob and Beacon of Creation.

ellie-is nice Elves! I will swap them for the 4x Llanowar Elves so 2xElvish Pioneer and 2x Skyshroud Ranger.

Love the deck! Got my +1. Scute Mob is devastating, but you need more land draw to get it up to speed. Cultivate is good (you should use more), and you should use other land draw, like Rampant Growth. Making sure your bugs can punch through with Rancor would be the bee's knees (pun intended). Not sure what to take out though.

Christopher I agree with you and I also do not know what cards to swap out. Maybe Song of Freyalise and instead of 2x Elvish Pioneer up to 3x Skyshroud Ranger so that would allow 4x Cultivate and 2x Rancor if I drop 1x Forest im back at 60 cards... Difficult decision
