Lure

Enchant Creature    (CMC:3)

All creatures able to block target creature must do so. Lure does not prevent a creature from blocking more than one creature if blocker has that ability. If blocker is forced to block more creatures than it is allowed to, defender chooses which of these creatures to block, but must block as many creatures as allowed.

Lure does not give a creature the ability to block the Lured creature, it just forces those creatures which are already able to block the Lured creature to do so.

If a Lured creature is in a band, only blockers able to block the Lured creature are affected by the Lure.

The opponent does not have to activate any abilities in an attempt to make his or her creatures block. More specifically, a cost to block of zero mana is an optional cost you can choose not to pay.
