The Dungeon Master

Indestructible, Hexproof

When The Dungeon Master enters the battlefield, search your library for up to two Equipment cards and equip them
on up to two members of your party. If there is a full party when The Dungeon Master enters, you may search for up
to four Equipment cards and equip them on up to four
members of your party.

If The Dungeon Master is your Commander, roll a D20 whenever this card enters the battlefield. If the result is 10
or lower, do not activate the ability above.
