going for UG kicker now. there are 7 payoffs: Coralheim Chronicler, Merfolk Falconer, Risen Riptide, Roost of Drakes, Vine Gecko, Lullmage's Familiar and Verazol, the Split Current. Some of them make kicked spells better by making you loot, scry, gain life, make a token or make a copy of a spell; or make themselves better by allowing to get a card, getting a counter or getting a boost.
we can count as well that all the spells allowing to ramp up in mana help to pay kicked CMCs: Ancient Greenwarden, Lotus Cobra, Reclaim the Wastes, Roiling Regrowth, Scale the Heights, Tangled Florahedron, Vastwood Surge, Vine Gecko and Lullmage's Familiar again, Skyclave Relic. Murasa Rootgrazer, Omnath, Forsaken Monument and Throne of Makindi have built-in ramp elements, but they are dependent respectively on having lands in hand, a second land coming in play, having colorless mana sources, and having a lot of time to play with charge counters - too much of a stretch to be repeatably used to support kicked spell payment.
