- 1 Myr Galvanizer i dont think he is good enough in an not only Myr Deck, he doesnt produce Myr Token, so it is either bad anyways

-1 Master Warcraft - well i wouldnt play it
Myr Battlesphere, Baneslayer Angel, Sword of Fire and Ice, Sword of Light and Shadow -> must play





-1 Indomitable Archangel - i thought itself has shroud too, but only your artifacts gain shroud, this doesnt protect you from Nevinarryls Disk and Oblivion Stone, so it is bad.+1 WR Legendary than can throw your creatures to your opponents head and you gain life too.+1 Mind's Eye must be played, you will need any sort of carddraw in this deck.-1 Sword of Vengeance - it is really important to have first strike and vigilance? the haste you got from other equipments are cheaper.
-1 Darksteel Plate - dont know if its good enough in EDH
+1 Red Mirrodin Artifact Land

Darksteel Ingot and Signal Pest should stay in your deck. Ingot = Indestructable, Singal Pest best Aggro one cc drop.

You should play Glorious Anthem instead of True Conviction.
Whispersilk Cloak and Armed Response can be cutted, because cloak is too bad compared to Boots and Greaves. Armed Response is a really bad removal.
Play Flametongue Kavu as removal creature too.
Crib Swap is also a good removal.
Austere Command should also pe played.
Shimmer Myr can be cut from the deck.You should play the 4mana kamigawa block artifact, that allows you to play nonlands spells as flash.
With the lot deck tuning cards i don't know what you should cut from your deck. Maybe Paladin en-Vec is another candiate.


How about the 30 lands in your deck, is it enough, because you got a lot of 6cc, 7cc and equip costs cards?

Swiftfoot Boots and Sensei's Diving Top are missing too

for your deck: banefire, mirran crusader, stonehewer giant.



to make your commander better: Myr Turbine, Precursor Golem, Shrine of Loyal Legions, Triskelavus.
