Well discuss the set mechanics more in a moment when we look into the individual archetypes, but there are a few central themes that affect card evaluation
Commanders Sphere is generally considered the baseline: it only taps for one mana, but its one mana of any of your decks colors, and you can always sacrifice it to draw a card
Omnath really loves lands, so team them up with anything that lets you play extra lands, plus other permanents with Landfall triggers, and its not hard to go-off, gaining an insurmountable value and mana advantage
Also, a shout out to Mirage Phalanx which is also in my Type Four wish list
Ready to upgrade your deck
Ive been enjoying it so much that I havent dismantled it in the pursuit of another deck (the fate of the vast majority of my EDH decks)
