A Single Card

Crime and Punishment!

Trap Card

When your opponent activates an effect that allows him to gain Life Points, you may pay Life Points equal to how many Life Points they gained from the card's effect, and declare 1 Type of Card (Monster, Spell, or Trap). If you declare Monster, your opponent cannot Summon a monster on their next turn. If you declare Spell, your opponent cannot activate or set a Spell Card on their next turn. If you declare Trap, your opponent cannot activate a trap on your next turn or set a trap on their next turn.

CnC is appreciated.

I'd use that card. It beats most of the traps in my deck in terms of effectiveness right now.

Not bad...

They should be allowed to set Spells and Traps, because you shouldn't know whether they are spells or traps.
Considering how little use this card would get (they need to increase their LP, so all you'll see it against are psychics really), it's really not all that good. Sure, its effect is great, but it wouldn't really be usable in the current meta (or most past ones). There are a lot of good Spell/Trap effects that have to do with LP gain, and this is more than likely the best, but, that being said, it isn't all that usable.
