If you're looking to put some extra flavor to this deck, Wall of Runes would be an option.

Happy Hunting!

If you were going to get rid of any of your mass land destruction cards, my recommendation would be Tsunami. It only destroys Islands. In an Anti-Blue deck that would could be epic, but is only useful against decks that run blue or Stormtide Leviathan.

As for consistent card draw, my recommendations would be Akki Scrapchomper, Grabby Giant and Nahiri's Lithoforming. All of these would also put lands into your graveyard.

May you draw well!

Have you considered Cleansing Wildfire? It's card draw, ramp and you can always play the land you destroy from the graveyard. I hope this helps. Happy Hunting!

Enchantment

Mythic Rare

Whenever a land you control is tapped for mana, ~ deals damage to each opponent equal to the of mana that land added to your mana pool.

Create a commander that can partner with any legendary land. The mana type(s) the land produces adds to the deck's color identity.

It That Stays

Creature- Eldradi Horror

Common

~ has Affixed (Spells and abilities cannot cause it to be exiled).

The Blind Eternities has its own kind of hold.

1/1

Create another card with affixed. It cannot be an Eldradi creature.

Dr. Doom, King of Latveria

Legendary Creature- Human Artificer Warlock

Mythic Rare

As long as it's your turn ~ is a Noble in addition to its other types.

Artifacts, Instants, and Sorceries cost less to cast.

At the beginning of each end step if a card named Reed Richards, Reckless Scientist, is in a player's graveyard, you win the game.

3/3

Repeat.
