The first step to improving a deck is finding its goal and shaping from there. What is the goal for this deck? How does it plan to win?

I would say some of the smaller stuff, like Typhoid Rats. I also don't think Splinter Twin needs to be here.

Bloodflow Connoisseur, Bloodthrone Vampire and others of a similar kind (along with token generation perhaps) might be fun additions to get more +1/+1 counters on Thraximundar.

This deck would be very powerful if Bazaar Trader was still standard. It is clever having those sacrifice abilities though.

That works too!

I feel that if you make a Stuffy Doll deck, you need to be doing damage to the Doll yourself. I have an idea for a green Doll deck myself, which is to use Beast Within on your opponents stuff and enchant the doll with Lure. The 3/3's combined with their own creatures should deal good and unavoidable damage.

Rancor is going to make infect much better. Signal Pest is also a good idea; well done.

Cool deck! Blink cards like Cloudshift and Conjurer's Closet would be fun with the Stonehorn Dignitary and Angel's Feather. Not much black, but very casual.

Instead of Jin-Gitaxias, you could try adding a fat artifact creature and Grand Architect to ramp it up.

Have fun with shuffling that!

If you had more artifacts like Necropede, you could have a chance with Mirran Meddle!

Gideon's Avenger should definitely be mainboarded! That is, if you are a Spike. If you're a Timmy that enjoys the experience of not letting anything untap, then this would provoke the best of said experience.

This deck is well put together! The Helvault + Divine Offering combo is very cool.

The Bower Passage and Creeping Renaissance are mainly sideboard cards . . . replacing them with ramp spells wouldn't be a bad choice.

Cool deck, but I don't think the Mana Leaks will be enough to give you breathing room. I believe there could be no better inclusion to this deck than Aether Adept.

Even Oblivion Rings, since they are a part of what this deck utilizes most.

I understand that you should be pretty safe when playing this, but I feel that it needs a quicker win condition, or else someone coul dplay a bomb spell by the time you're attacking witha Sunblast Angel. Perhaps a few counters wouldn't hurt.

Thanks for commenting on my deck, and good luck at FNM!

I suggest Wurmcoil Engine, since he dies-making two 3/3's-and then you can bring him back.

This would be a useful tribal if snakes actually benefit from being on the battlefield together.

The flavor of this deck is absolutely perfect! I would love to see this in standard, but at the same time I am really excited about Return to Ravnica. Thank you for commenting on my deck.
