Dr. Mobius, Mad Genius

At the beginning of combat on your turn, you may
pay {r}{r} and create two 2/2 colorless Roboscorpion
artifact creature tokens. They gain haste until end of
turn.
Mentat Addiction —Whenever one or more artifact
creatures enter the battlefield under your control,
create a colorless Chem artifact token, then scry 1
and draw a card. At the beginning of your upkeep,
you lose life equal to the number of Chem tokens
you control.
