Umbric

That was the joke :D

Yes, you will have to sac it. It does allow it to stay a turn longer though

I would add obzedat or blood baron

Memoricide or reap intellect?

I've been waiting to see someone use ball lightning/spark trooper and legion's initiative

take out both life links for obzedats, take out 2 basilisk collar for 2 vizkopa or 2 warhammers

Obzedat, and blood baron of vizkopa

I would take take out stonehorn for another venser

Oh I was recommending it, I thought you didn't have it, my bad. Restoration angel is too expensive right?

Manamorphose is a good option

cloudshift or restoration angel to have creatures make more tokens as the enter the battlefield

Cloudshift so you can re use their Detain enter the battlefield ability along with ghostly flicker

Cloud shift?

Standard only he said

or aurelia's fury, or both

Take out gavony ironwright because you want more life not less. Add another cathedral sanctifier, add cloudshift and some restoration angels so you can gain life quickly and efficiently. Also add Rhox faithmender and serra ascendant

searing spear and a pillar of flame

Elvish piper, quicksilver amulet, Urza's mine and the other urza lands, also All is Dust because
A.) Name is badass
B.) Art is badass
C.) It's game changing

Legion's initiative with vexing devil and spark trooper?

He makes manaleak, humble, jace, azor's, peacekeeper cheaper to cast, and he can totally screw your opponents. He is never useless because his is very versatile and can make geist of saint traft and steel cost less too. That extra turn you get to cast something can help a lot similarly to it can make your opponents spells cost more. It can be game changing
