Menhir of the Opaque

Coduit (When you cast your first Conduit spell this game, choose a conduit color.)
Whenever you cast a spell of your conduit
color, if Mehir of the Opaque is untapped,
wizard and artifact creature spells you cast
can be cast this turn as though they had
flash and cost {1} less to cast. If it's tapped,
wizards and artifacts you control gain
dreamwalk this turn and you draw a card.
