JOurney to nowhere is not as good in this deck. Your creatures are most likely unblockable by being too big or being evasive (sidewinderx2 generally means you are unblockable).

Substitute journey and 1 stirrings for 4 Armadillo Cloak . It is amazing in this type of deck, and you are never displeased to see it.

For the SB, you do not need celestial flare that much, you already have enough GW hexproof hate in scorn and the conspire spell. I would recommend 2 more Gleeful Sabotage for affinity and 1 more of each Crown of Awe and COP:red to improve the MBC matchup and burn/gobbos.

I like it. I can see you're going for an aggro vibe here so how do you feel about Reflex Sliver ? Just a couple. Your mana curve can easily support it.P.S I LOVE Slivers! XDP.P.S Good job.

While my curve could probably handle it, Reflex Sliver just feels a bit too expensive for my taste without enough reward. This is only being said after a bunch of testing.
