Cards that give you benefits for playing big creatures are good options
Then theres Maui Demigod, an eight-cost bruiser with eight strength, eight will power, and three Lore
All of Them I could quibble over Signets, Talismans, Fellwar Stone, Mind Stone, and so on, but truth is all the 2-mana rocks basically play out the same regardless of extra utility
Even just paying one mana to turn this spell into a basic land card is going to be useful in some games, but being able to find any creature you need, especially in a format like Commander, can be the difference between winning and losing
There are some counterspells and removal that give this deck a bit of a control subtheme, but it doesnt lean too heavily on it
I guess one attack from a Swans of Bryn Argoll, Tarmogoyf, or Slogurk, the Overslime should get the job done, but what about on an empty board
