Scorpion Master

When Scorpion Master enters the battlefield,
search your library for up to three cards named
Dune Scorpion. Put one onto the battlefield, one
into your hand, and one into your graveyard.
Scorpions you control get +1/+0.
As long as you control three or more Scorpions, Scorpions you control have lifelink, menace, and deathtouch.
