1 "Nordic Beast" Tuner + 2 or more non-Tuner monsters
Once per turn, you can negate the effects of all face-up monsters your opponent controls, until the End Phase. During the End Phase, if this face-up card on the field was destroyed by your opponent's card (either by battle or by card effect) and sent to the Graveyard this turn, you can remove from play 1 "Nordic Beast" Tuner monster from your Graveyard to Special Summon this card from the Graveyard. When it is Special Summoned by this effect, inflict 800 damage to your opponent.
