mtg ultima card Final Fantasy Reveals Boardwipe Time Warp in One put a blight counter on target land. MTG Ultima, Original of Oblivion

Im even planning to build my own food-themed Commander deck around it

Cards like Seedborn Muse and Wilderness Reclamation are excellent if you have a lot of land, lands that produce more than 1 mana, or mana dorks so you can produce more mana, even on your opponents turn

It's going to help you from multiple angles

There is no single answer to thisit depends entirely on what your deck wants to do

6 Maze Of Ith Like Ivory Tower, Maze of Ith can make duels long and arduous as it can heavily control what happens on the field of battle

You can also blink this with things like Ephimerate, and it gets even more out of hand
