All creatures able to block enchanted creature do so.
11/17/2017 Lure doesn’t give any creatures the ability to block the target creature. It just forces those creatures that are already able to block the creature to do so.
11/17/2017 As blockers are declared, any creature that’s tapped or affected by a spell or ability that says it can’t block doesn’t block. If there’s a cost associated with having the creature block, no player is forced to pay that cost, so it doesn’t block if that cost isn’t paid.
