There are a few good synergies here to bring up. First, Minh and any version of Grisly Totem.
With Minh, each one of these can be +2 Wild, therefore making it roughly equivalent to 3 Unexpected Courages, which you can pull back from discard at will. That's honestly pretty great, and at its best, is pretty close to a never ending stream of Unexpected Courage.
With Grisly Totem, you'll get the exact same effect. If you have the Seeker Grisly Totem, you could even be drawing a card each time as well.
With Minh AND Grisly Totem, you can stack those effects. That means you'll be able to get +3 Wild icons, 3 times, on a card you can pull back to your hand from discard for 1r.
Of course, to maximize these interactions, you want to commit one and only Glimmer per round, as these abilities have per round limits.
Keep in mind that pulling back 3 Glimmers at once is a burst of 3 cards in your hand. This can empower other effects which note how many cards are in your hand, such as Curiosity, Higher Education, and so on.
Outside of Minh and Grisly Totem, the other great use of Glimmer is as discard fodder for something like Wendy, Pete, or Cornered. You can happily chuck these cards into your discard pile whenever and draw them all back when you need to. Of course, other cards are discard fodder (Winging It, et al.), however those cards can't bounce back into your hand nor do they have icons in case you need commitments. Due to its easy recursion and flexibility of use, Glimmer is the most reliable discard fodder currently in the game.
