Activate only when If your opponent controls at least 3 monsters that were Special Summoned from the Extra Deck or from the hand: When this card is activated, select Target 3 Special Summoned monsters your opponent controls; on their field, destroy 1 monster and send it to the graveyard of those targets, also banish the a 2nd monster target, and take also control of the 3rd monster remaining target and deal inflict damage to your opponent equal to its DEF.

Tight restriction, but powerful payoff. Under normal circumstances, "destroy" will send the monster to the Graveyard anyway, and Pendulum mechanics dictate a Pendulum Monster destroyed this way still falls back into the Extra Deck.

 

Do all 3 monsters need to stay on the field for this card to resolve properly? I'm hoping not, because otherwise it'd be incredibly easy to sabotage this card. This is why I've inserted the "also"s - so that if you lose one of the targets the remaining effects can still work on what's left.
