Essentially, get tokens into play, and polymorph until you hit one of the fatties. There are 2 Akroma's in there mainly to increase the chances that you'll hit one of those first. You'll never want more than 1 fatty in play.

I've chosen rewind as my main hard counter simply because I'm always going to have something to do in the first few turns - in the way of tokens etc, and it's more useful as a hard counter to take on gigadrowse.

Utopia Sprawl is a decent acceleration tool that won't be hit by polymoprh.

I've elected Telling Time and Think Twice of other card draw for their instant qualities, and Telling Times ability to ensure that I don't draw my creatures when accelerating through.

The deck has problems vs heavy counter control, so the SB is mainly geared toward that.

SB:
Sacred Mesa is great vs control - if you can get it in.
Gigadrowse is vs control to ensure the polymoprh goes off
Shadow of Doubt for D-Storm and anything with Flagstones or Mystical Teachings.
Blazing archon vs aggro - to be morphed in of course.
Defense Grid - again Vs Aggro.

I like this deck much better than your UR Snow deck. While this is janky, I can actually see this working against most of the field. My suggestion, Condemn or Temporal Isolation instead of Fetters. Condemn/Iso is huge against everyone.

I've been testing this alot over the last few months, and it works really very well. The Faith's Fetter's were only put in here today whilst I was writing it up - mainly because I can't remember what was in there as I'm at work and writing it off the top of my head lol

Sprout used to be in there - Mainly for the early token. An Instant speed 1/1 is quite good, as it helps speed up the polymorph attempt, and it can be used as an early blocker. This was dropped as, whilst it can be good early game, it's a dead wight if you draw it later. I decided to stick with CotH and Vitu Ghazi for repeated, and uncounterable respectively.

I'll certainly give iso a look - condemn didn't work in here that was when I played - the fetter's is mainly in there against cards like Sacred Mesa, Vitu Ghazi, Urza's Factory etc that do cause problems for me. It's also helpful against aggro with the lifegain.

This decklist suffers from the same problem as your UR Snow list, although to a much lesser extent (mainly because you have a true sweeper in Wrath). You lack early game defense against aggro. I think you as a deckbuilder underestimate the ability of Boros/Zoo to just run you over. You have to account for that. Fetters is nice, but it really won't cause most aggro decks to blink if it is your first major answer to them. Fetters following a Wrath is strong, but you have to get there first. This list works better in that you can generate a call token on Turn 3 to block, but I still think you should have Iso/Condemn. The main reason being, Mesa, Factory, and Ghazi all can be dealt with via other ways:

Mesa: Your fatties have trample, that handles the Mesa.
Factory/Ghazi: Run your own, which allows you to match token for token, or run Ghost Quarter. For super savage tech, do both!

Would you be willing to test it with me? I'd be more than happy to play against you with it and make some decisions from there. But so far on MWS etc, Boros hasn't really been a problem in the majority of games.

Yeah sure. I'd be willing to test, but my sideboard is pretty rough right now. I'd be happier with testing results if I had a real sideboard .
