Bulls are counterable by Tall-nuts, so an Umbrella Leaf deflecting them would be like an Umbrella Leaf deflecting Pole Vaulters.

Also, Prime's lasers would surely damage and destroy the Umbrella Leaf or maybe pierce through it because they're lasers.

And Wizard attacks don't come from above, so Umbrellas would make no sense protecting against them.
