If I take a look at the average decklist, in addition to the lands and Sol Ring, its relying on a couple of mana rocks, Cultivate, and Kodamas Reach to fix the colors and get enough mana to cast Atraxa and your higher-cost spells
When Eddie Brock enters, you'll return target creature card with a mana value of 1 or less from your graveyard to the battlefield
Throw a few of these out for the cheap cost of two mana each, then move from one to the other for one lore, and youll be gaining a mountain of card advantage and running away with the game before your opponent can do anything about it
Cloud, Planet's Champion If you're looking to build a Voltron commander, Cloud, Planet's Champion checks all the boxes
Very appropriate
