Here's a list of every card banned from Brawl decks: Chalice of the Void Drannith Magistrate Lutri, the Spellchaser Oko, Thief of Crowns Omnath, Locus of Creation Runed Halo Sorcerous Spyglass Winota, Joiner of Forces Pithing Needle If you're planning on playing a game of MTG Brawl, it's important to point out that the banlist for the Standard format doesn't apply to it

Heres my shortlist of noteworthy upgrade options, divided by price point rather than card function: $1 OR LESS OPTIONS Marionette Master, Armix, Filigree Thrasher, Gravebreaker Lamia, Disciple of the Vault, Voltaic Construct, Ill-Gotten Gains, Stinkweed Imp, Orbs of Warding, Silent Gravestone, Scourge of Nel Toth, Mimic Vat $10 OR LESS OPTIONS Priest of Yawgmoth, Staff of Domination, Crypt of Agadeem, Pili-Pala, Basalt Monolith, Bolass Citadel, Metalwork Colossus, Nettlecyst, Currency Converter, Grim Hireling, Ruthless Technomancer MORE THAN $10 OPTIONS Entomb, Reanimate, Altar of the Brood, Retrofitter Foundry, Cabal Coffers, Defense Grid, Blightsteel Colossus, Darksteel Forge, Revel in Riches, Pitiless Plunderer THEY PUT THE NASTY IN DYNASTY This precon has been one of the hardest to make upgrade recommendations for not because theres any shortage of good options, but because theres just too many equally strong directions to take the deck
