I confess I loved the time aspect, where the color would synergize with suspend, time counters, and the like a similar approach to blue (it does what other colors cant, basically)
While there may be other cards that offer similar effects, Primula's versatility and synergy with Plant archetypes make it a strong contender for inclusion in such decks, especially if the strategy involves frequent tributing of monsters
This solves a lot of problems very well and cost effectively
However, you may still play other cards, and the Trainer card Switch can be used in the normal way, for example, to Switch your Active (and Asleep!) Pokmon with one on the Bench, and this will remove the sleep condition
As gotcha's go, this one's always struck us as a little odd
