Spider-5K

Refit 4 (When Spider-5K enters the battlefield, you
may reveal cards from your hand with total converted
mana cost 4 or more. Shuffle those cards into your
library.)
When Spider-5K Refits, create four 1/1 colorless Urbanmech artifact creature tokens with lifelink.
Two machine guns and some medium lasers don't
scare many people, but when a spider falls out of the
sky, you're about to have more problems.
