Disney Lorcanas Set 8 expansion, Reign of Jafar, introduces over 200 new cards that are set to shake up the meta and bring fresh diversity to different deck archetypes
Giver of Runes also makes a lot of Cubes, and its a fine card but is just kind of a one-mana Flagbearer which has pretty low value over replacement relative to just playing another powerful threat
If you're in a combo meta or want this to be a higher-powered deck you really should go all in on those Ivy Lane Denizen combos
Barrin, Master Wizard (Saga/Legacy/Destiny) Barrin, Master Wizard, though a very fragile 1/1, basically turned every card on your side of the board into an Unsummon
LANDS Labyrinth of Skophos Labyrinth of Skophos is a new and improved Mystifying Maze, a card I never see played in Commander (except when I tried it myself)
If a manifested creature would have morph or disguise if it were face up, you may also turn it face up by paying its morph cost or disguise cost
