Forum:Double Tool C&D Combo Lock

I have recently started to play. I have built a rather nice assortment of Morptronic monsters which in able me to lock my apponite rather quickly, However I do have a few questions about some of there effects..

For example:

If I equip two monsters with say a "Double Tool C&D" which has the effect of Enemy monsters must attack the card equipped with this card. Would my opponent then be able to pick between the two monsters or would they not be able to attack as they would be able to pick two targets?

Just wondering how this would be ruled, or for example of other morphtornic cards which have the effect "You must attack me!"?

Thanks,

Grovester
