Primal Amulet's last ability triggers once you've completed casting a spell. Notably, you can't use Primal Wellspring to pay for the spell that gives Primal Amulet its fourth counter.

Primal Wellspring's delayed triggered ability can copy the spell even if that spell is countered before the ability resolves.
2017-09-29
The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).

If a fourth charge counter is put on Primal Amulet by something other than the resolution of its ability (as modified by any applicable replacement effects), you won't be able to remove those counters and transform it yet. You'll have to wait until you cast an instant or sorcery spell again.
