Multiplayer suggestions?

[Kitokofox]

I just thought of some cool multiplayer items:

At the beginning of every hole all the players get an item they can use on themselves or others. However, the choice must blindly be made before beginning the hole, and at your turn you'll find out what has happened! The item distribution is also handled as per ranking (If you're in first, you're likely to get defensive items or little boosts) and last a hole.
