Yeah the khans block cycled out when SOI came into the Standard format.

Too many creatures to take out to really let Polymorph work.

Khans sets aren't Standard anymore, I've no idea why this site won't remove them from the list.

I think you need more discard sources like Call the Bloodline and Tormenting Voice.

Also control like Fiery Temper and Lightning Axe never hurts.

Ideas Unbound, Compulsive Research or Thirst for Knowledge I would put over Catalog.

What of Wall of Roots?

I play Traproot Kami over Wall of Vines. I have had the debate between the two many times. But I personally prefer something that gets bigger.

But Wall of Roots puts City of Solitude out turn 2 or mana accel in general.

This is awesome. I have a playset of all the pirates and was looking for something to do with them. This looks like it would be great at my local shops casual tournament.

That helps the opponent post Shared Fate.

Playing leveler prior to playing Shared fate is an instant win. I played brainspoil to transmute into the one copy.

Shrapnel Blast is uncommon, maybe Galvanic Blast in it's place?

So if I don't have my keys to any combo but have 3 bell strikes in hand, what do I do?
I use the bell strike on their biggest pain is the @$$ to preserve health.

My game winners aren't the hardest to find via Genesis Hydra, and my kitty, especially if I am already going on infinite mana.

Why have one win factor if you can have multiple without changing much of the deck?

1. I usually have atleast 1 land that won't come in tapped, my land has never been an issue.
2. A hexproof devotion guy that can block fliers, and I can target to grow infinitely, is a bad thing? I've won 4 games with this dude.
3. Bellstrike is the key to the combo and only control main board. Without keys of the combos, I don't win.

All in all, this is a retired deck that did very well. I've moved from standard, its too costly for cards that I won't use long.

Below is the deck I used in standard at the same time this was standard. My sideboard was all control. Your sideboard looks good, but my number one save was Stubborn Denial. They usually only had enough mana to just cast the counter, but not the extra 1.
Purphoros is not needed. You need Nylea to give your big baddie trample, or another way to win with pumping.
Hydra broodmaster and hornet queen are too much fat and not enough to hit combo.
You need 4 singing bell strike.
With my deck there were enough ways to go infinite that if they killed my first attempt, I had another just around the corner.

Leveler is an instant win. I built mine with relentless rats and cards like Surgical extraction so I knew I was going to get the cards I needed.

I was thinking the same thing. Sorin's Vengeance could replace sign in blood.

I have a playset of Waste Not and always wanted it in a deck but this deck is going in a different direction I think.

The Dash mechanic is pretty good with this commander. Also Goblin Piledriver is pretty good for mostly Goblin decks.

How often does Nissa flip?

Ancestral mask should be good here.
