Angrboda, the Bringer of Grief

Menace, trample
When Angrboda enters the battlefield, you
may search your library for a Giant card,
reveal it, then shuffle your library and put that
card on top of it.
The giantess old in Ironwood sat, in the east, and
bore the brood of Fenrir; Among these one in monster's
guise was soon to steal the sun from the sky.
