Some additional notes: To determine the total cost to cast a spell (or activate an ability), you start with the base mana cost after making all the necessary decisions (modes, targets, value of X, etc.), consider the effects of any additional costs (kicker etc.) or alternative costs (flashback, overload etc.), add the effects of any cost increases (Sphere of Resistance etc.) and then subtract the effects of any cost reducers (Animar etc.) and finally apply Trinisphere if needed (yes, it has a special rule all of its own).

The rules of the game do allow for a cost to be reduced to {0} this way. If an effect only allows reduction to some minimum amount it will specifically say so (e.g. Heartstone).

Battlemage's Bracers, Heartstone. I'd look at the cards with Friend/Foe effects.

The "all creatures gain trample and haste" ability would be awesome with some Goad cards like Baeloth Barrityl, Entertainer

OH! I just realized. I need a Heartstone Think I will drop archwing dragon and move that to the maybe list for now. I just don't see dropping 4 mana each turn just for a dragon that has 0 impact when it hits the field other than making the commander ability go off. It might be useful, but I think heartstone is far more useful than a archwing and I have plenty of creatures so far.

I also removed the Fire Diamond and the other Diamond and wayfarers's bauble for mana rocks I felt were just better.

Unfortunately the Heartstone doesn't work with Satoru. Here is the explanation from the judges: "No, Heartstone only affects creatures on the battlefield, not creature cards in your hand." (https://chat.magicjudges.org/mtgrules/)

Looks fun!

Workhorse goes infinite with Emiel. Infinite ETB triggers. Infinite mana with Heartstone out.

Charming Prince is a neat card. You don't go infinite with it, but if you're against decks that permanently steals cards (Etali, Primal Storm, Xanathar, Guild Kingpin, etc) this can get them back. And if you have enough mana, you can bounce it repeatedly to save creatures from boardwipes.

Be careful with Yisharn, its ability prevents you from going infinite with Brood Monitor, since you have to sacrifice the eldrazi for mana.

You may want to consider adding some low mana ETB creatures for tempo. Right now Emiel is cheaper than most of your pay off creatures, so you're going Ramp -> Turn 3 Emiel -> Turn 4 Creature (4/5/6 drop) -> Turn 5 actually getting to activate Emiel for extra value. Wall of Blossoms, Elvish Visionary, Wall of Omens, etc are good chump blockers, replace themselves, and can accelerate you earlier than the big creatures that are targets for removal.

One thing I don't get is why Polyraptor is there, it's a good card but I don't see much synergy with Emiel?

Ridgescale Tusker and Primeval Protector would be fun to blink with your boss. Maybe Druid of the Emerald Grove and Heartstone

Soul of the Harvest would give you another Trample creature and Blinking activates the card draw ability.

I also have Heartstone for the Emiel and Workhorse combo if I don't have the ability to give him an additional +1+1 counters.
