Aurelia, the Warleader:
I pulled Aurelia after selecting Dimir at the Gatecrash Prerelease. As you can imagine, I ditched the pre-selected colors and threw together a Boros build that went 3-1. If she hit the board, I won. I now run an Aurelia EDH deck which threatens to end someones game the moment she hits the board.
Muzzio, Visionary Architect - lets you cheat artifacts into play at instant speed, including things like Blightsteel Colossus.
Advent of the Wurm gets you an instant speed fatty that can be populated.
Mimic Vat works surprisingly well in a populate deck since the duplicated token sticks around.
I'd suggest more but I'm on my phone. I'll try to check back later.
Whatever you target the opponents dragon with, you copy it for each creature you have and target them with those copies. So if you have three creatures and hit their dragon with Path to Exile, you will be exiling all 3 of your creatures and tutoring up 3 lands (if you choose to do so)
See, that's another issue in itself.
You should be running at least:
Possibly any of the following:
Solemn Simulacrum (this is debatable with green, but since you aren't mono green, I still recommend him. He's good fixing for if you get stuck drawing only white sources and what not.)
Kodama's Reach/Cultivate ramps 1 land, and keeps 1 land ready to play this turn or next.
Farseek/Skyshroud Claim - Generic ramp
Earthcraft - not exactly 'ramp', but it keeps mana flowing. Especially in a token deck.
Depends which one you mean. Biorhythm does it, but is banned in EDH. Shaman of Forgotten Ways does it and doubles as a mana dork which is nice, but it's an expensive ability to utilize and instant speed removal Cyclonic Rift could be brutal.
Gaining life just to delay being killed means little typically because someone will most likely combo off or kill you with commander damage.
If you want to keep the lifegain theme up, add things like Archangel of Thune and Phyrexian Processor to get value from it.
In general, I like Freyalise in my green token decks to pump out little token dorks while also providing removal. I would cut Essence of the Wild. Unless you constantly produce swarms of tokens after its out, it seems overcosted and shut down utility creatures you may draw. Beastmaster Ascension does a better job of pumping your creatures new and old. Also, one of my new favorite token makers Righteous Confluence has a good variety of useful abilities for this deck.
That doesnt even make sense.
That doesnt work. The tree has to stick around to complete the exchange.
