Assuming you only get back 1 monster, here is the wording based on how I understand it: Once per turn, during your Battle Phase, if your opponent activates a card or effect after an attack is declared: Banish the attacking monster
It isnt even the first card of its kind, with Laboratory Maniac as the previous staple
I could use a bit more ramp, one GY hate, and a bit less targeted removal, but overall it's solid enough
Youll often see this turned against you as the other players retaliate against you for turning them into your own personal puppet show
Unfortunately I have no video to confirm it, but at that time I had not yet open any Series 2 pack, so no way to mix them later by accident.
There haven't been many sealed booster boxes recently sold on the public market, so you'll likely only find booster packs if you're lucky
