City of Brass , and Mana Confluence would be helpful.

Rhystic Study , Prime Speaker Zegana , Coiling Oracle , Sea Gate Oracle , Seedborn Muse , Vorinclex, Voice of Hunger , the signets, Green Sun's Zenith , Genesis Wave would all be suggestions I have for ya.

Looks like you need more ramp, and draw. Hope this helps.

Didgeridooda I don't like those lands even thought its EDH and I have 40 life. Rhystic i will consider. For Prime Speaker i decided to put in Ephara, God of the Polis cause with this type of deck she just works better and is also harder to remove. Seedborn Muse is nice and all but is a bit pricey for me atm. I like the Prophet even though it doesnt untap everything, but it also gives my creatures flash so i can get the most out of Ephara. For Vorinclex my mana curve would be to high so i have Mirari's Wake which helps out tokens and mana.Seagate i'm not a fan of. Green Sun i feel like there's nothing in my deck i really need to grab. Same with genesis. Lastly for coiling Oracle i don't know what i'd replace. Thanks for your feedback

Most of those cards I mentioned were not as replacements for what you mentioned, but to run with. If you have nothing you want to grab with green sun, then you need better creatures in there. It is also good early ramp with Dryad Arbor . Gen wave is a win in this deck if you have good ramp.

You talk about your curve, which brings me to ramp. You really need to ramp hard with roon because you need to play big cost spells, as well as have mana left to blink. Mirari's Wake is awesome, but you need much more early ramp.

Deadeye Navigator is the best blinker out there. Reliquary Tower is also a must. With primespeaker you can be drawing as many cards as you want. As well as all the slower consistant draw. Thragtusk would also be very very good.

The wake is a card that I am trying to get ahold of. It is so good.

Cards I would suggest you remove. AEtherling, Emmara Tandris, Great Sable Stag, Kalonian Hydra, Twilight Drover, Honor of the Pure, Collective Blessing, Gaea's Anthem, Glorious Anthem

Tokens are a tough play in EDH due to the number of board wipes. So I would only use the really strong stuff.

Didgeridooda The one thing I like about this deck tho is even if it gets board wiped, which it has been already many times, I can build it up again very quickly because of how many token generators I have. Twilight is really strong because this is a mostly token deck so taking it out wouldn't be smart.

If it is strong, and plays well keep it. I was just going off of how I see token decks play.

What is the strength of the decks that you play against? If it is not a super competitive group you can play much different stuff, and still be successful.

Some token ideas. Rootborn Defenses , Elspeth, Knight-Errant

Didgeridooda well the main one i play against is a zedruu deck. others include trostani, Selesnya's Voice brion stoutarm child of alara and sen triplet. And Elspeth, Knight-Errant is too expensive but if i get the modern event deck i'd prob swap that one and the one i have or just add her. The one i have currently helps alot

Is it more of a fun group then a super competitive group?

Didgeridooda yeah. we play casually.

Ok, I gotcha. I play in a pretty cut throat group so optimizing is key. Ramping up to get out a wincondition, and make sure to have an answer early is the name of the game. I have struggled with casually playing EDH because I hardly play anyone that does. So I just see ways to optimize, and overwhelm so I sometimes over do it when trying to help out with more casual decks. Hope I was able to help a little at least.

Didgeridooda do you have an edh on here? i'd love to see it.

I have 2 on here, and 2 that I have not put up yet. Wub Wub Deck, and Omnastic. I have used what I have from my cards, and they are not nearly perfect, but they get the job done. Omnath is quick, 5 turns quick. My wub wub has been in some 4v1 situations many times, and when it gets to that point, I usually have it on lock down really well. Gotta put my fetches back in my B/U/W, and get some duals for it. I have been trading for the pieces I need one at a time.

With my roon, I emphasize ramp heavily. Then blink my draw guys, and I often get to gen wave for alot on my opponents turn(10-30+), then swing for the win.

Then I have a mono black Mikeus deck. Has a few combos, and a bunch of ramp to do something like an Exsanguinate for the win if I don't combo off.

Deadeye combos with many things to do infinite mana, as much draw as you want, multiple use counterspell, there are so many possibilities with him. Mystic Snake + him is usually when my opponents scoop.

I'm with Didgeridooda on the ramp. mana advantage is so key on Roon. His colors make this pretty easy. My Roon deck relies on attempting to dump as many permanents on the board as soon as possible for the most part. Check it out if you're looking for some card ideas, I think I have it pretty well balanced. Most really expensive cards are in the sideboard that are really good. I use permanents to ramp as it goes with my theme, but Cultivate , Explosive Vegetation , Rampant Growth , Coiling Oracle , Harrow , and Skyshroud Claim are all decent green mana ramp/fetch if you don't mind using sorceries. I personally love anything that allows you to cheat more lands onto the field after your land drop for turn.

I have a similar deck and Craterhoof Behemoth is an absolute must. Duplicant is also fantastic for removal. If you play heads up, Stonehorn Dignitary is just evil. I really don't see why you need all those planeswalkers. I have found that for the blink stuff to work you really have to commit to it.

trgoose I have the planeswalkers in there for various reasons. One being how is it not fun to drop either elspeth after a doubling season and have your creatures buffed and your things indestructible. With Ajani I gain 100 life. Venser is blink and most of the time people concede to me ulting venser. and kiora is there to stop big attackers while trying to get my own quickly. With stonehorn i can only stop 1 person from attacking unless i have my prophet or murkfiend out where i can try to blink multiple things.

Thragtusk would be ridiculous in this. Flicker effects will trigger both abilities, for exit and reentry. Love the deck.
