Card Tips:Simorgh, Bird of Kings

Special summon Mist Valley Apex Avian at the end of the turn with this card's 3rd ability at the end of the turn, and you can negate. This can also be done infinitely if Mist Valley Apex Avian returns Mist Valley Thunderbird to the hand, for its negation effect, as Thunderbird can return itself to the field immediately, and more than once per turn.
