Utvara Hellkite maybe? just a thought
Extra dragons whenever a dragon attacks

Yes unfortunately i can't give you much in the way of advice for legacy tournements, mut i can see the synergy happening with the fetch lands and the lavamancer.

I would advise observing a legacy game or just asking someone what the metagame is to see what kinda creatures run well, but all i know is that tarmagoyf is big and exiling creatures will prevent some of his power, other than that i wish you luck with legacy

This seems quick and powerful i am guessing this is a tournement deck by the looks of your land base?
Just thinking that Pillar of Flame is a good answer to annoying creatures because they are exiled and you can also target players.
Just something i thought you may consider becasue i can't think of any other improvements, nice work

Seems like a good deck, tokens are always good fun to run with, if we aren't staying standard then maybe have a look at some things like
-Luminarch ascension
-Entreat the angels
-Akroma's Memorial
- Requim Angel
- Kazandu Tuskcaller

Up to you, and i would deff main board Rhys, he is as overpowerd as anything!
Take a look at my Commander deck based on him for more token fun ideas

After playtesting descovered that Royal Assassin's are much more overpowered than originally realised. When a creature taps to attack you, you can tap Royal assassin in your declare blockers stage to destroy the creature before it deals damage to you. So more of them are going in. Also discovered that dark ritual into crypt ghast or desecration demon is a really good turn 2 so i am thinking of adding more of them but don't know what to take out

That is true that you may have to pay with life due to not having the white mana, but it also forces you opponant to pay with life if they are not playing white. I took down a tournemant quality dredge deck with 2 norn's annex in a casual deck just because he was having to pay 4 life to attack me with 2/2 creatures

This is a genius idea i love it :D u could just paack your deck with any big creature cards even if they werent of your colours and pull out this combo!

How about exiling one of your tokens you have created? remeber oblivian ring hits the battlefield before targeting thus giving you a token and then you target

Not a bad idea thank you, what would you say to take out for it?

It does because you play it you don't just put it into play

Omniscience?

Paradox haze? just for extra upkeeps

Just fir lockdown, martial law?
Very similar idea to my deck

i like it

I'm a big commander fan, i love the format and have played a lot of commander games so i have seen a lot of the good cards for commander decks. Have a look at some of mine if you want inspiration

Stompy Creatures

Milling
http://www.mtgvault.com/sharpraptor/decks/damia-goes-milling/

Renegade Krasis
Ooze Flux
Mimeoplasm
Damia,sage of stone
Primordial Hydra
Pedator ooze
Doubling Season
Thrummingbird
Vorel of the hull clade (doubles +1/+1 counters)
Vulturous Zombie
Varolz, the scar-striped (gives all creatures in your graveyard scavenge)
Death's Presence
Golgari Grave Chant

Also, you can't have wild hunger in your deck due to it having a red mana symbol in the flashback cost and that not being in your commanders colour identity

Master of the wild hunt?
Dawntreader Elk?

If you can get hold of them boros reckoners would help you because they do the same basic job as stuffy doll but arent indestructable
and i agree with the blasphemous act idea

that's what i was thinking

How about requim angel? whenever a non spirit you control dies put a spirit token into the battlefield, means you can sac your guys twice

it doesn't bounce back to hand but unflinching courage is a good aura
