Runick helps out Witchcrafter's with being able to put a body out on the field for monster gate to add to consistency. Added advantage of being able to use Runick Spells to get out WC monsters and Runick spells fueling Vice-Madame's ignition effects.
WC doesn't really care about the battle phase as much as the main phase so they can get some advantage still with having to wait until the following battle phase to clear your opponents life points. WC is nice against the meta as if it get's milled by Tears, then that's to our advantage and WC doesn't really care about Maxx C...the only bain against this deck is Ash Blossom...So do consider siding in Called by the Grave if you're finding you're getting stopped a lot by Ash Blossom.
Ideal board includes getting out Verre, Haine, Vice-Madame along with setting up for a Avramax.
