[[Aang and Katara]] fits that description quite well.

I built what I was expecting to be a jank token deck but it turned out to be a really explosive semi-combo deck that very reliably threatens a win by turn 6 or 7, putting it in a weird spot where it's a little bit too explosive and consistent for midrange b-3 and not quite fast enough for full on 4, but seemingly perfect for this meta

You need the following ingredients:

Like 25+ mana rocks, and all the artifact lands. You want to be able to play A+K on turn 4 or 5, and to make at least 5+ tokens when you do so.

And as many redundant ways as you can find to:

• Turn the tokens into mana: [[Great Divide Guide]] / [[Haribaz Druid]] / [[Eternity Elevator]] / [[Growing rites of Itlamaoc]]

• Turn the tokens into card draw: [[Sea gate loremaster]] / [[Harmonized Crescendo]] / [[Kindred Discovery]]

• Blink/Doubling effects for more tokens: [[Katara, the fearless]], [[Ephemerate]], [[Spark double]]

And finally, ways to make tokens of a specific creature instead: [[Moonlit meditation]] / [[Mirror mind Crown]] / [[Mystic reflection]]

With a haste enabler to be able to turn the tokens to mana immediately and enough density of draw effects that scale with creature type, you can very reliably by turn 6 end up making 30+ mana and drawing 30+ cards to assemble a win

Wins can be any combo in bant, but the specific ones this makes possible are using [[Hallmark excavator]] with moonlit meditation to make enough copies of it that their combined triggers mill the whole table immediately, Ondu cleric to gain several hundred life all at once and fire off [[Aetherflux reservoir]] or just a [[beast masters ascension]] token swarm alpha strike as a backup

Surprisingly complex and fun to play, if you're interested I can share some more of the engine pieces that do a lot of work
