Hi, everyone.
I just came home from my trip.
So, first of all, yes, it targets. So, you pick a card you want to shackle!
Oh, and one more thing, this is not limited to creatures. You can target weapons and such too.
Jappert,
Interesting alternative. But, I personally think that has a bigger potential for OP than the current setting. It also doesn't really make sense for a shackle to be able to restrain more than one target. So, for the time being, I'd like to leave the effect as it is.
And, no, I did not intend this card to stack (double of already doubled cost? no way! lol).
