Helm of the Coven

Each Witch, Warlock, or Wizard you own that
isn't on the battlefield gains madness. The
madness cost is equal to its mana cost.
Whenever a Witch, Warlock, or Wizard enters
the battlefield under your control, if its madness
cost was paid, you may put a deathtouch or a
lifelink counter on it.
Witches, Warlocks, and Wizards you control get
+1/+1
