[Combo?] Heartless Myrs

[Bigface]

Hello everyone, I'm someone you probably don't remember. I'd like to discuss an idea for a deck I had looking at the INN spoiler (and that was probably already used by someone). It's based on what should be (if I got that right) a 3-cards infinite loop for 2 mana. Without much further ado, those are the cards:

Heartless Summoning + 2x Myr Retriever

Since Heartless Summoning reduces without any limitation the mana cost of creature spells, you can cast Myr N°1 for free. Myr then dies due to Summoning's effect, but not before triggering its ability. Therefore, you can cast a second one for free, fetching the first one and so on.
This loop grants no mana/life without any other cards, yet allows you to accumulate an arbitrary large storm count FTW. The objective of this discussion is: Can we build a deck based on, or at least playing, this combo?

This "combo" ain't great, I know. It relies on the GY, can be disrupted easily due to its creature-depending nature and needs at least an additional card to win. Yet, I think it could be implemented in a combo shell or a control one.

A combo shell could implement a Intuition engine (fetch 3x Myr, play Summonings, loop) combined with other tutors (adding W can give us Enlightened Tutor and lots, lots of counterspells/discards. The colors should be UWB with a red splash and/or mana-producing artifacts (Lotus Petals should be enough if you need R for your kill spell and/or Burning Wish): white should be expecially important since it gives us a good tutor for both combo pieces and Orim's Chant to pull it off undisturbed. Due to the "infinite" nature of this combo a simple Grapeshot is lethal, requiring 4 mana only (2 if you played Summonings during another turn).

A control shell could also be UWB, with a heavy use of discard spells, counterspells and various W goodness to keep us alive until we can pull off the combo. Landstill comes to my mind, yet I don't think there would be much synergy between the deck type and this kind of combo. A monoB Pox shell could be nice too, using Myrs to re-use artifacts like Ratchet Bomb and use Bitter Ordeal to finish your opponent.

I hope I didn't annoy you and would like to know:
1) If the combo itself works;
2) What your opinions are.

Thank you all, and bye :D

Sadly, this is a 4-card combo, and even though it doesn't require much mana to play, it's still 4 cards which is pretty janky.

However, Muddle the Mixture, Dimir House Guard and Shred Memory is able to fetch ALL the cards in the combo. That is at least something, even though you can only Transmute at sorcery speed which sucks. The upside of this is that you're playing blue and black. That's right, you don't even need a Grapeshot to do the combo, Brain Freeze will do the trick. Unless you prefer Grapeshot, you can keep the deck two colors which will improve the stability of its manabase. Hypothetically, the deck would have to play as a combo control deck of some sort.

Bloody fun with Goblin Welders circa 2001, but best as mono-brown combo. Gotta love dog robots.

Heartless Summoning seems to work better with Scythe of the Wretched and Triskelion. At least that way you actually get a 3 card combo.
