What are the best infinite colored mana combos for a 5-color deck?

I’m building a not good at all deck based around the There’s the Door idea.

That list is very old, though. I’ll be replacing the commander with [[Kenrith, Returned King]] to have the infinite draw all in one card, but I’ll need infinite mana of every color for that and to get the rest of the deck’s plan going.

Besides the [[Isochron Scepter]] + [[Dramatic Reversal]] that list uses I’ve thought about [[Peregrine Drake]] / [[Great Whale]] / [[Palinchron]] + [[Deadeye Navigator]] and [[Bloom Tender]] / [[Faeburrow Elder]] + [[Pemmin’s Aura]] / [[Freed from the Real]].

Is there some place where I can search for infinite colored mana combos? I tried the EDHRec combos page but it doesn’t let me filter by combo type, so I’d have to look at over a thousand of them just to find the ones I’m looking for, which I’ll do if there’s no choice but it’s quite troublesome.

Or if anyone knows of another infinite colored mana combo (preferably with just two cards) and can tell me about it I’d appreciate it.

Thanks!
