[MTG] -Ruling Question about SoulBond-?

Yes, it's a triggered ability.

You can sort of respond to it. You can always respond to the soulbond trigger, however note that the choice of whether or not to pair two creatures is made as the ability resolves. That means that if you want to respond to it, you have to do so before knowing whether or not your opponent intends to pair the creatures. Once you let them decide, it's too late to do anything about it.

As always, though, if your opponent rushes ahead without giving you the chance to respond, you have the right to back things up (and your opponent just gave you some free information to boot).

1. Soulbond is a trigger, yes.

2. Well, that's where it gets more tricky, since the general rule is tournament level based on play. For example if your opponent casts a spell, and you have a counter in hand, and you ask who he's soulbonding it too, it's assumed you've let it resolve. So no counter for you. If your opponent says "Soulbonding to" as part of casting it, then you can say "Nah-uh, I'm responding to your casting by shocking Z" though they can however, be allowed to choose another creature, depending on the REL.

yes he can both creatures get the soulbond effect and you can respond to it.
