Suggestion: Weaken the target creature by 2/2 (3/3 if upped) and add 2(3) photons in your opponent's hand. Do not add photons when your opponent's hand is full.
This just makes the card way too nice.
Instead, you can make it add 2(3) photons to op's hand, and if he doesn't have any space - to the top of his deck.
Imagine having like 6 of these upped in your hand and waiting for op to get a full hand and play them all in 1 turn. Oh, the horror!
