I would say:

You choose a card at random from your opponent's hand, and your opponent chooses the circle: Double edged sword, you may make them ditch a PG, or you may make them call a powerful interceptor.

You choose a circle, and your opponent chooses a card from his or her hand: Your opponent can literally call anything with on-call ability to mess up your plans, and can even increase his or her vanguard's power up to 10000 [Power] with some sort of units.

You choose both: Anything can happen.

Your opponent reveals his or her hand, and you choose one from it: A bit OP, but if it is restricted to only very very a few boss units, it seems fair and is really a strong solid playstyle.
