A Red Counterspell?

I like it when you can fit an effect or ability into another color in the color pie by adding a limitation or twist to an existing effect or ability. For example, "Stealing" or gaining control of a creature for a single turn was a blue ability for a long time aka spells like Ray of Command. And back then it was in fact played like a blue ability. Good players would use it defensively 90%+ of the time, getting a 2-for-1 by waiting for an opponent to attack, then blocking the attacker with a stolen blocker. But making it a sorcery turned it into an aggressive, "temporary gain" effect that fits red well.

Another example is the effect of destroying a tapped creature or attacking creature. That limitation makes it defensive/retributive in nature, making it fit into white. Bouncing an opponent's creature, especially at sorcery speed, is red since it is an offensive application of the effect. I think it could be used more.

A second way of making an effect fit into another color is to tack an extra ability onto it. Black doesn't usually damage creatures outright, and never gains life as a stand-alone effect. But because of the flavor of "feeding off of the misery of others," it can have both of these if it gains life off of damage. This is more of an aesthetic reason rather than any kind of game balance consideration.

So with these two types of ability-shifting in mind, I think red could have a counterspell like this:

I think this "Venser" ability feels like a red way of countering spells because it throws away card advantage for a temporal gain. By tacking damage onto the effect, it would be playable even when it is less efficient (as well as card-disadvantageous) compared to blue counters. It wouldn't just be a worse counter, it would be a different counter.

Maybe this ability could be called a "distraction" "daze" or "stun" effect.

One possible problem with this effect is that it could be too devastating for slow decks that utilize lots of midrange permanents rather than spells.

I understand that during Planar Chaos, WotC considered moving Memory Lapse into white, but testing showed that a white delay spell would be too good in the weenie swarm color that white is. The card above might present the same problem (although it suffers card disadvantage that Memory Lapse doesn't have) since red is even more aggressive than white.

But it could be a matter of adjusting the cost; Memory Lapse had to remain at the same cost because it was being considered as a colorshifted card.

A second problem is that it's kind of wordy. The text could be simpler if it just returned a spell to its owner's hand instead of acting like a mana leak. However, I think having a number involved (like "pay 2") can help connect the spell-bouncing effect with the flavor of "interrupting a spell with a painful blow" better.

Anyways, lots of variations of this are possible. There could be an X spell version. There could be a version that returns a spell that costs less than the damage dealt (like a Spell Blast rather than a Power Sink).

Here is a creature card with that ability:
