Something we all do (or I do and assume others do as well) is when a new mechanic comes out we start making cards almost immediately that go with it. I like to look at a mechanic and try to figure out how they're going to use it to make staples for that block/draft/competitive. This could be a thread about costing mechanics appropriately, where to push the envelope, and see if we can guess some of the cards they'd make.
Populate just came out with the first spoiled card for Ravnica2.
"Populate = put a copy of a creature token you control onto the battlefield" essentially. Based on the card Rootborn Defenses I would say this is a Selesnya only mechanic (Green White) and it adds about 1 colorless mana to a card. This is a lot to assume with just one card but it's enough to start speculating. Some other ideas:
If they don't reprint farseek then a selesnya version of rampant growth might be:
Pollinate - 1G
Instant
Populate. Search your library for a basic land card, reveal it, and put it into your hand. Then shuffle your library.
Pollinate 2 - 2G
Sorcery
Populate. Search your library for a forest or plains card and put it onto the battlefield.
Sporeatic Mantle - 2G
Enchantment - Aura
Enchant Creature
Whenever enchanted creature attacks put a 1/1 green saproling token onto the battlefield tapped and attacking.
Return Sporeatic Mantle to your hand: Populate.
