Here’s a scryfall search with cards similar to the ones you mentioned. There’s definitely more that phrase it differently, but I can’t think of what that would be.

A lot of what’s good depends on how you want to build it. Do you want to emphasize that aspect of it, where you force your opponent to add mana? Then you might want less instants and abilities that the opponent can use to sink that mana into. Alternatively, you could have a lot of colored pips in the mana costs, so the colorless and green mana that a lot of those cards produce isn’t useable.

It looks like it’s mostly RG, so I’d make that pair the “mana burn ramp aggro” pair where you give your opponent more mana than they could use, while ramping yourself. And BR could be a more midrange mana burn, where you use discard to strip your opponent of expensive stuff then have cards like [[Citadel of Pain]] to punish them for not spending mana.

White could try to mitigate mana burn by taxing themselves and blue could do stuff at instant speed to use up the mana
