If this card inflicts battle damage to your opponent: Skip the Draw Phase of their next turn
This Card Sleeve has a more straightforward solution: they give you a single slot on the front of the wallet that can hold one or two cards and are easily removed without an issue
For example, a creature that enters the battlefield under your control with one +1/+1 counter on it won't receive an additional +1/+1 counter
I would suggest, instead, protection from a single card effect that would affect it, and in the case of a continuous effect, protection until the end of the turn
VERY RARELY will you get a deal to work where you get the better end of the deal, and that requires a lot of patience and waiting
