If Braid of Fire is teamed with Soulbright Flamekin, does it carry the mana into the main phase because to my understanding Soulbright Flamekin's effect for trample lasts until end of turn but the adding the mana is just for that phase which at the time is during the upkeep phase and would then drop off come the start of the main phase so is my understanding correct?
The mana will empty from your mana pool at the end of your upkeep step.
If you really want to net mana this way, just activate it twice in your upkeep, then a third time in your main phase.
