I suggest the way to do ability words is to have the mechanic "name" be something like "blank target creature." (including the final dot), and then have the reminder text be a separate sentence like "Until end of turn, that creature loses all abilities."

I like this kind of ability - one of the first cards on Multiverse was Mindblanker. It's pretty potent to have it as a draw trigger, but I guess it does normally only neuter a creature on your turns. Plus it turns Brainstorm into an awesome combat trick, which is always fun.

I was lazy and didn't want to go and copypaste the reminder text after.
