Unwavering bonds, next good countertrap?

Unwavering Bonds
Counter trap
When your opponent activates a Pendulum Monster's effect or the effect of a card that is already in the Pendulum Zone: Negate the activation, and if you do, banish that card.

This card seems to have great potential, allowing you to negate any effect a pendulum monster might have no matter where it is and banish it. This would be a VERY good card against a pendulum deck and definitely side deck worthy if it weren't for a little card known as twin twisters. That card counters this card very hard making it almost impossible to activate this card and hit something relevant. What do you think, is this card worthy of maining or better as a side deck card and pray it doesn't get Twin twistered.

this is definitely a anti-pendulum card that could see some time in the side deck.

This card doesn't seem useful anymore. Most pendulum monsters in play have continuous effects, and others have destruction costs. I mean, you can slow them down; but by all means you can't stop them. After the PePe hit in the OCG, this card is pretty useless now in the side deck when much better options are available.
