So cut Sarkhan, that opens up 2 MB and 1 SB and also cuts out the green and blue lands. You're also saying cut Sarkhan's Triumph I do believe? and Boltwing Marauder too? So that opens up 9 slots, so maybe put Sarkhan Dragonspeaker in SB as a one of and 3 Stormbreath Dragons in MB with 3 Soulfire Grandmasters and 3 Crackling Dooms? How would I fit the duress or thoughtseize in?
Same with Crux of Fate and Anger in SB.
Also, on the topic of Walkers, what about Sorin, if i'm splashing white for Crackling Doom? Or Liliana or Ajani at that? Or maybe an Ugin? Idk. Just playing around with options.
Note: I was trying to build this deck based on what we know will be in standard come end of September when Theros block rotates out.
Edit: Does it look better now? I put Anger in as 2 of; maybe get rid of Rending Volley and put in 2 more? or move an Ultimate Price and a Foul-Tongue Invocation and put 2 in MB? Also, playing around with mana base: how important is it to have Bloodstained Mire for search or any of the tap lands in a deck like this? According to the stats I only need 16 Mountain produce, 6 Swamp produce and 3 plains produce, so i modified the mana base to fit that. Would it work properly without the tap/search lands (other than temple of malice) or no? Or should I play around with Evolving Wilds?
