You need to be in at least three colors for this to become mana-positive
Here are the must-have cards for the deck: 3 Niv-Mizzet Reborn 4 Bring to Light 4 Sylvan Caryatid 2 Paradise Druid 4 Teferi, Time Raveler 2 Abrupt Decay 1 Supreme Verdict 1 Utter End 2 Uro, Titan of Natures Wrath 2 Siege Rhino 26 Lands Thats 51 cards, which leaves us with only nine flex slots
Perhaps the ace will continue to be Ohime the Manifested Mikanko, and I think that mainly will be used here
Creatures (30) 4 Merfolk Branchwalker 4 Jadelight Ranger 4 Stitcher's Supplier 1 Golgari Findbroker 1 Golgari Raiders 4 Glowspore Shaman 4 Kraul Harpooner 4 Plaguecrafter 1 Rix Maadi Reveler 3 Judith, the Scourge Diva Lands (23) Spells (3) 3 Find (Note: Rhythm of the Savages x4 is also in my list right now, but that is an unconfirmed card name as of this writing.) I may be overestimating how good the Kraul Harpooner with haste combo is compared to just playing Golgari Raiders here, but the baseline of Kraul Harpooner is an actual Magic cardyou can not say that for Golgari Raiders
It kind of is, in the sense that itll stop them expending tokens until they find removal
