Everything being said, that he does not have haste, that he is situational, can be said about sharpshooter. At the same time we use sharpie to great effect in the correct situational context.
I think he is the same. Tec you can put into your sideboard to use against slower creature control games. Enchantress, The rock or Sometimes agro like Infinity if they have yet to find plating.
Is it worth cutting something main deck to run it? Situational. See a fair amount of situations locally where you could use it and maybe you would.
But as I said before, it's a meta call. But if we are willing to run one card (Confusion) to deal with one deck archetype that can give us grief, this guy could be just another confusion, just answering a different situation.
My view anyway.
Dice.
