mtg beacon cards Magic The Gathering - Commander Legends From the Fifth Dawn set. Command Beacon #470 Galaxy Foil

Let me know in the comments, or on Draftsim's Twitter/X

It doesnt do any proliferating on its own, so its purely a payoff card for a proliferate-themed deck

Urabrask is also a legendary to build a Commander deck around, which works well for your deck building needs

Cards like Talisman of Dominance, trading at $2, or Talisman of Conviction, also trading at $2, allow you to tap for colorless mana immediately upon entering the battlefield
