unless you are trying to keep this deck type 2, you should add prismatic omen, and scapeshift

this deck is very nice, the only thing about samrai is, is that they cost so much mana. i would add in Urza's Incubator to make your samurai cost less, and i would add cloud key also.

Orachi Hatchery!!!

try sword of feast and famine

Undead warchief for sure, he is a must. also add 4 darksteel citadels and 4 phylacterary lich

GRAVE TITAN

add four darksteel citadels and 4 phylacterary Lich

also run Goblin warchief instead of emberhauler and goblin lackey instead of spikeshot elder

also take out contested war zone, mystifying maze andteetering peaks and add x4 scalding tarn and for the rest just basic mountains

I would for sure run fetchlands, they get the land out of your deck so you can draw more of the carrds you want to use, also drop lightning bolt and arc trail and add Goblin Grenade x3 and goblin warstrike x3

Id definently try belbe's portal in this deck.

Prismatic omen for sure, really brings valakut to life.

for sure, oracle of mul daya and primeval titan to bring out the land for valakut. also i agree, you should try comet storm

swarmyard is a must have for this deck, you can use it to attack each turn without minding your opponents power, also i would try cover of darkness, or perhaps dark ritual

id try myrsmith instead of masters call, with the fast mana you are bringing into play, you could bring out many more myr tokens.

Id definently suggest myr turbine. it doesn't cost too much and it can help you bring out myr battlesphere
