Mutate 2(U/B)GG
Trample
You may cast Brokkos, Apex of Forever from your graveyard using its mutate ability.
6/6
I might be overestimating this, but this card seems really solid to me for Sultai. It doesn't do the usual silly graveyard things Sultai usually cares about, but (assuming it doesn't get exiled), any creature you cast can just become a 6/6 trample (plus whatever other abilities it has). Get wrathed? Topdeck a mana dork? Now it's a 6/6 trample again.
Am I overestimating the recursion here? For reference, my one Sultai card is currently Tasigur.
I think you are overestimating the recursion because it's recursion of an aura that either makes a creature a 6/6 or gives a creature trample, for 5 mana. That seems pretty meh to me. Especially since it's a 3-color 5 cmc french vanilla 6/6 on the front end.
for 5 manas, it either makes a creature a 6/6 trample (+ abilities of this creature) or it gives trample which will happens rarely.
Seems pretty good to me for a recursive effect
Plus the mutate cost is not 3 colors but only 2 which could make it playable for example in a BG deck with entomb, self-mill...

As noted by sandino, it's functionally a 2-color card from the graveyard (but you'd have to get it there first if you aren't in all 3 colors. While it'll definitely be a minor upgrade for some creatures, you can give a smaller creature without trample both the 6/6 stats and trample, which isn't nothing.
There are a moderate number of creatures it'll be mediocre-to-irrelevant for (like Griselbrand or Craterhoof Behemoth), but the vast majority of creatures (even in green) don't have these base stats and/or don't have trample, especially since many of them have their value tied up in ETB abilities or activated abilities.
I'm not sure it's compelling enough to seek out, but I'll definitely take it for a few spins if I open one. It's a nice recursion ability that just requires another creature. The ceiling is definitely lower than the value you can get out of Muldrotha, but it's floor seems fairly respectable, since your deck is likely to have a reasonable number of creatures with decidedly lower stats, and it doesn't have to stick on the battlefield to gain value.
My opinion is probably also colored by the fact that I have 1 card for each tri-color in my cube. The current one is Tasigur, and there's no way this is better than Tasigur.

In BUG colors (in my cube), the only cards this doesn't help at all are:
Inkwell Leviathan
Doom Whisperer
Carnage Tyrant
Primeval Titan
Woodfall Primus
