Evolving, however, for just 3 extra energy per revive is just really bad especially seeing how 2 of the intergidents needed to evolve it are SS and the last one is S (which would add up to about 20,000 Magic Powder, which is just a really bad trade-off).

Just upgrade your Wonder Donut and leave it at that. There are much better treasures to evolve anyway.
