+1. I like the look of this, looks like it can get pretty scary.

Few comments though. Scute Mob doesn't seem necessary at all and World Queller seems more detrimental than useful - especially when you haven't got your combo going off yet. You should focus on getting the combo out ASAP.

I see that you are trying to ramp and defend with walls on the field, you should add Wall of Omens in to help with that and provide card advantage. You also don't have enough blue permanents to guarantee Mirror-Sigil Sergeant 's effect to trigger. Perhaps more blue walls like Wall of Frost or Psychic Membrane ?

A neat little combo I realised with Paradox Haze is that and Awakening Zone , which would provide you with a LOT of ramp and chump blockers.

Is Chronomantic Escape and Genesis Wave providing any use to you? I playtested your deck and both cards didn't really help with much until really late-game. You don't really need them.

Anyway, heres my suggestion:

-2 Scute Mob

-2 World Queller

-2 Chronomantic Escape

-3 Genesis Wave

+3 Wall of Omens

+2 Wall of Frost

+2 Psychic Membrane

+2 Awakening Zone

Thanks for the comment and the +1!

I agree that Scute Mob doesn't really do much for me... I originally put it in because it's nice that its ability can trigger multiple times per turn with Paradox Haze , but since it doesn't have trample I usually get approximately 0 value out of it...

On having more blue permanents, you're probably right on that too. In terms of walls, I was thinking more along the lines of Guard Gomazoa for its "prevent all combat damage" ability. That makes it the perfect defender against pure beatdown decks, and lets me block things that might otherwise be too big to handle without losing a creature.

World Queller isn't bad simply because its ability is optional, so if the combo hasn't gone off yet I don't have to use it, and I can simply use the thing as a planeswalker/artifact gun if need be. I'll take it out, but put it in the sideboard.

Awakening Zone is a great idea, and would provide me with another source of ramp, letting me get rid of some Followed Footsteps , (which I usually used to clone Overgrown Battlement for more ramp).

On Chronomantic Escape , it doesn't come out very often, but when it does it generally saves me. With two Paradox Haze s out, I can literally never be attacked again, because I'm taking three upkeeps a turn. I'm probably going to cut it down to 1 and see how it goes.

Genesis Wave , on the other hand, I get a really surprising amount of value out of. I'm usually able to pull it out for 6 or 7 and get a Mirror-Sigil Sergeant and a Paradox Haze or Parallel Lives out. I'm keeping it in, but I'll test it out with it as a 2-of and see how that works.

So what I think is going to happen is:

Mainboard

-2 Scute Mob

-2 World Queller

-2 Followed Footsteps

-1 Chronomantic Escape

-1 Genesis Wave

+3 Guard Gomazoa

+3 Wall of Omens

+2 Awakening Zone

Sideboard

+2 World Queller for people who use artifact or planeswalker heavy decks

+1 Chronomantic Escape for really aggressive decks to stave off attacks better

+2 Path to Exile against things I just can't deal with fast enough

+3 Leyline of Vitality against burn

For now at least. What do you think?

Whoops. I meant Leyline of Sanctity , not Leyline of Vitality . But now that I mention it, I think I'll simply make it 2 of each in Sideboard.

I'm considering swapping out my Followed Footsteps for Soul Warden s as a bit of protection against early game aggro and burn. What do you think?

Chronozoa is another funny card that might fit in this deck.

It just sucks when you have so many Paradox Haze in the battlefield that the Chronozoa double each turn and are stuck in a perpetual state of sickness.

Yeah, the eternal summon-sickness thing is why I'm not using Chronozoa . It would make a nice blocker-creator, but I have lots of walls, Eldrazi Spawns, and Rhinos for that, so it doesn't really work. Thanks for the suggestion though. :)
