Yeheldred, Witch Queen

"Whenever a Witch enters the battlefield
under your control, target opponent creates
a charm token. (It's a colorless artifact with "{4}, {t}, Sacrifice this artifact: Search your library for a card with converted mana cost {4} or less, reveal it, put it into your hand, then target opponent creates a charm token. Then that player shuffles their library.")
