I think the best solution would be that this card cannot be used on times cards.
If you want, you can have to upgraded version of this card also cost 1 quanta.
While this card is similar to both precog and RT is some ways, all these 3 cards are different:
Reverse time: Costs one card to play and 2 or 1 quanta, resets a creature, gives quanta control, and gives draw disadvantage (slightly OP card IMHO)
Return: Costs 2 or 1 quanta, reset a creature or permanent (does not cost a card to play, no quanta control, no draw disadvantage)
Precognition: Costs 2 or 1 quanta, lets you see the hand (does not cost a card to play)
While the abilities of the cards might seem similar or even overlapping, the tactical usage is completely different.
The point is not that you can return a creature just like reverse time. You can return a creature OR you can use it for something else. For example, you can return you current weapon and replace it with something else. Or you can return a creature of you own to buy a more expensive one (think multicolor decks).
For example, I have a wyrm in play (4 air quanta) and I want to play a firefly queen. But I only have 3 air quanta and 2 time quanta (because I played a supernova). If I use the return on the wyrm then I have 7 air quanta and 0 time quanta and I can play the firefly queen (but I keep the damage that the wyrm did on previous turns instead of saving my quanta for my queen and waiting to play the wyrm).
Reverse time simply cannot do this. You make clever use of return even if you opponent doesn't have any creatures ... so it is different from reverse time in the ways it can be used.
Not to mention that return affects the hand instead of the deck. In the future, there might be more cards that affect the hand in one way or another. For example, you might return a card and then make him discard a card.
