From a game I played yesterday: My opponent rescues with Abraham after he has decked out. I have Music Leader in my territory. Does Abraham trigger ML?
Abraham - "Negate opponent’s neutral cards. Search deck for a Genesis 12-24 Hero. May band to a Genesis 12-24 Hero. Cannot be negated."
Music Leader - "If an opponent uses a draw or search ability (except on a musician), you may search deck or discard pile for up to 2 good cards that involve music."
