I'm getting ready to move, so I can't actually play with my cards that are packed. As a result, I'm doing a lot of theorycraft in my head.

Filigree Familiar -> Pilgrim's Eye
I'm never happy to draft FF, it always ended up at the end of the draft. I may regret this having just put some flicker cards in.

Daretti -> Chainer
I like the cut of Chainer's gib. Daretti doesn't have an artifact deck to play into, and I like how Chainer fits into both cheaty and recursive strategies in BR.

Beast Whisperer -> Nightpack Ambusher
I don't feel like there's a case where Beast Whisperer is what I want to do on curve, but Nightpack Ambusher adds some fun play with flash.

I thought about removing Fleetwheel Cruiser here.
I feel like the aggressive decks have plenty of options in the four mana slot. It's definitely on the chopping block.

I picked up some new cards and I'm giving then a try. Lots of changes in the multi colored sections, with smaller changes in the mono groups. 

I'm trying to settle on a good balance for a few colors while introducing new cards from the recent sets, and it's HARD. Wizards needs to give me a break.

I feel like the mono-B aggro deck is a trap at 360 just because I don't have enough black 1-drops to support it if even one gets picked up by another drafter.

Instead, I'm pulling out a couple of the aggro enablers in black and I'm replacing them with a devotion top-end.

Obliterator might not make it into a lot of mainboards, but when that deck comes together it'll be fun!

Squeezing in some more cards from WAR and jumping on the MH1 cards I pre-ordered.

There are also a few changes based on practice drafts to fill gaps or reduce redundancies where I found myself boarding out cards or avoiding them entirely.
