have you looked at Strionic Resonator?? It takes off suspend counters, doubles annihilators, even your Eternal Dominion would be happy for the addition... Just food for thought.

My favorite part about this deck is that I can swap out a few cards and narrow the price down to $300 or lower with just a few changes. Anyone looking for a more budget version without losing a lot of functionality, Volcanic Island becomes a Mountain, Grim Monolith becomes Thran Dynamo, Force of Will becomes Cancel, Mana Drain becomes Arcane Denial, and Mana Crypt becomes a Thought Vessel. I built the deck using these changes and it performs beautifully.

Love the deck. I always like when people choose to make their EDH deck fun to play rather than hyper-competitive.

A couple of suggestions if you don't mind:

Chandra Nalaar and Jace Beleren seem somewhat underpowered relative to the rest of the deck. If you like having planeswalkers I'd recommend Chandra, Pyrogenius and Jace, the Mind Sculptor, otherwise a Pact of Negation and Swan Song offer spectacular control.

I think I like Redirect more than Commandeer because three cards (two plus the commandeer) is probably worth more than two mana.

Consider Sapphire Medallion for ramp since most of the spells you'll be hard-casting are blue.

Thanks again for the cool list!

Just a note OP, you should change where you host that image. Chrome flags desktop-image[.]com to be a phishing site, so when you click onto this decklist it comes up with a big warning and stuff. as seen here

How well do you find Eternal Dominion to play? I eventually took it out of the decks I ran it in because my opponents' decks usually had stuff that helped only them...
