Cosmic Death-Guide

Haste
Whenever you Exile a card under your control,
all Exiled cards under your control cost {1} less
until the end of the turn.

{t}: Ambush 1(You may exile 1 card from your
hand. If you do, place it face-down without
revealing. Starting at the next end step, you
may play that card as if it has flash.)
They are just my playthings. I am their Guide.
