Not Ranked: Acornelia, Fashionable Filcher A silver border prevents Acornelia, Fashionable Filcher from being your commander unless you have a Rule 0 conversation with your play group, but you could ignore the art-matters text to make that discussion easier
You can also include any of the easy two-card combos like Dark Depths + Thespian Stage (+ Expedition Map, Elvish Reclaimer, and Crop Rotation), Survival of the Fittest + Recurring Nightmare, or Strip Mine + Crucible of the Worlds, Wrenn and Six, Ramunap Excavator, or Icetill Explorer (+Crop Rotation, Elvish Reclaimer, Green Suns Zenith)
Hopefully fringe
Merfolk options like Tuvasa, Emperor Mihail II, and Svyelun provide strong enchantment and protection advantages
