When Im thinking of it as an extra turns commander, I expect a midrange deck that establishes a stompy board, then leverages Storms combat trigger to copy Time Warp so you can take three or four turns to overcome three opponents
For Gruul mana-fixing, I recommend prioritizing dual lands that count as both Forests and Mountains: Cinder Glade, Stomping Ground, Sheltered Thicket, and Taiga (if you're willing to spend lots of money) add layers of extra synergy to the deck because they can be fetched by lands (Wooded Foothills) and spells (Wood Elves) while also empowering cards that care about land types like Valakut, the Molten Pinnacle and Howl of the Night Pack
