Special Summon 1 "Nordic" monster from your Deck. You cannot Special Summon monsters from the Extra Deck while the Summoned monster is face-up on the field, except "Aesir" monsters. You can banish this card from your GY; add 1 "Nordic" monster from your Deck to your hand, then shuffle 1 card from your hand into the Deck. You can only use 1 "Nordic Relic Hlidskjalf" effect per turn, and only once that turn.
