When on the play, you'll need to be more reactive until you can stabilize the board
You've got good mana fixing with Ignoble Hierarch , Rampant Growth , and the full set of Talismans , you have a decent suite of answer cards like Maelstrom Pulse and Terminate , card draw from things like Syphon Mind and Deathreap Ritual , and significant threats in the form of Broodmate Tyrant and Archon of Cruelty
But, if you have fans of Magic: The Gathering or The Lord of the Rings in your life, the Scene Boxes make great stocking stuffers
As die rolling is an Un- thing and Commander Legends was a black-bordered product, the card focused on coin flipping
As such you can fairly reliably chunk planeswalkers for two in the mid game with a Predator which stops them from being cast or at least stops them doing much useful
Other ideas that were too pricey for the deck include Defense of the Heart, Dust Bowl, Strip Mine, Pernicious Deed, Oblivion Stone, Expedition Map, Mirrorpool, Traverse the Ulvenwald, Attrition, and maybe Primeval Bounty
