It makes your opponent discard a card from their hand whenever you play a Floodborn character and along with a few other tricks will completely wreck your opponents hand early and often
Group Hug is better than ever, so perhaps pick one of these for your next Commander deck
Card Illustrator: Rise of The Floodborn
Mana dorks Llanowar Elves, Elvish Mystic, Birds of Paradise, and Bloom Tender provide turn-one acceleration and creature synergies Land-search spells Cultivate, Kodama's Reach, Nature's Lore, and Three Visits build a resilient permanent mana base Extra land drops Exploration, Azusa, and Oracle of Mul Daya let you deploy multiple lands per turn for compounding advantage Mana doublers Nyxbloom Ancient, Vorinclex, and Zendikar Resurgent multiply your existing mana for explosive late-game turns Creature-based engines Selvala, Heart of the Wilds and Karametra, God of Harvests generate mana tied to your board state Building a Green Ramp Package For mono-green Commander decks, aim for 12-15 ramp pieces more than other colors because green's payoffs reward having large amounts of mana
You can also do the three-mana sorcery to mill 5 and send a creature from into your hand, which is nice in self-mill brews like Sultai that then want to do things with that milling
If there's one thing control decks aren't shy about, it's extra mana in the late game
