Speedsters Beyond has no team or trait build system in recorded builds. The real decision is which morph and evolution to fund; this page maps the entity types, their recorded EXP tags, and where each detail lives.
The Morph menu equips a single character, and the recorded sessions show that character's EXP tag changing the rate at which stats grow. Nothing in the checked footage shows a second slot, a class choice, a trait roll or a synergy bonus, so a build question is really a spending question: which morph, and whether to fund its evolution.
Four things behave like entities in this game, and only one of them is equipped.
An EXP tag describes how fast stats grow while that morph is equipped; it is not a combat rating, a hitbox size or a race placement. Because the developer publishes no scaling formula, any ranking of morphs is an argument about tag and cost rather than a measurement. Check the recorded costs here, then confirm the live price in your own Morph menu before spending Points.
