Original Post

So this is a rough idea that just popped into my head while discussing another deck.

Basically, the idea is to play a bunch of cards that can be put into play for free, use LED to discard and cast Echo for a fresh hand, and then do it all again.

My initial idea for putting cards into play for free is to build around an Affinity shell, using free artifacts like Lotus Petal, Mox Opal, Memnite, Frogmite, and Myr Enforcer.

I'd like to make Hollow One work, since it is an artifact creature that can be cast for free and contribute to casting Myr Enforcer for free. It's going to require additional discard outlets besides just LED, but needing additional discard outlets makes sense because of Echo anyway.

With just LED, Hollow One's in the initial hand aren't going to be castable (and will get discarded after cracking it), but if I draw a new hand with Echo, any Hollow One's in the new hand should be castable, so I feel like it should be able to work.

Careful Study makes the most sense as an additional discard outlet. My biggest concern is that they only reduce the cost of Hollow One to 1 mana instead of 0, but hopefully that's not an issue. I'll also need more cards that I actively want to discard to make Study worth it.

I still need more engine cards too. Echo and Study alone aren't going to be enough.

Emry, Lurker of the Loch can bin cards into the yard, which synergizes well with Echo, and the activated ability works well with Careful Study and LED.

Thoughtcast seems decent, drawing 2 for a single blue mana once there are 4+ artifacts in play.

Anyway, here's a rough list to get started...

Echo Affinity

Lands (4)
4 Seat of Synod

Creatures (20)
4 Emry, Lurker of the Loch
4 Memnite
4 Frogmite
4 Myr Enforcer
4 Hollow One

Spells (24)
4 Thoughtcast
4 Careful Study
4 Echo of Eons
4 Lion's Eye Diamond
4 Lotus Petal
4 Mox Opal

Beyond that, I'm not really sure what to do. I'm at 48 cards so far, so that leaves 12 more, but I still need to include a few more mana sources, some sort of disruption, and some sort of pay off.

There are a couple of directions I could see taking the deck in from here.

Basking Rootwalla and Vengevine have a lot of synergy in here. Study and LED enable Rootwalla to be cast for free; Study and Emry bin Vengevine, which can be easily triggered.

Glimpse of Nature could be a really strong supplemental draw engine, especially with more free creatures like Basking Rootwalla and Ornithopter.

Paradoxical Outcome probably costs too much mana, but I could see that being another powerful draw engine in here too.

Maybe the deck should run Brain Freeze, chaining spells and then casting on yourself to bin Echo or Vengevine? With an active Emry, I could get back LED to cast Echo to keep going.

Maybe Cranial Plating with some flying creatures, like Vault Skirge, Smuggler's Copter, or even Blinkmoth Nexus would be enough? There's also Thopter Foundry and Sword of the Meek, especially with Gaea's Cradle. Sai, Master Thopterist is an engine by itself for making fliers.

I really like the interaction between Etherium Sculptor and Springleaf Drum. It would also reduce the cost of Hollow One to 0 with Careful Study. I could even run Conjurer's Bauble, which draws a card immediately vs the slow tripping of the other Bauble's, and the effect could potentially protect cards from Surgical Extraction and graveyard hate.

Is it just dumb to not be running Mishra's Bauble and Urza's Bauble with Emry?

I'm sure I need some sort of disruption too. Force of Will and Force of Negation would probably be the best choices, assuming I can get my blue spell count high enough.

Narset, Parter of Veils would also be sick with Echo, and most likely needs to be included.
