Theinen the Great Sphinx is the third and last Sphinx monster to appear in the movie.
No. It is specifically stated on the card lore that it "cannot be Special Summoned except by paying 500 Life Points when both "Andro Sphinx" and "Sphinx Teleia" are destroyed at the same time..."
None of those cards are really worth much.
Sphinx Teleia came in every 'Exclusive Pack', a tie-in product pack for the Yu-Gi-Oh movie. This pack was also placed in the Master Collection 2 set. The mass production of this pack combined with the fact that the card is very poor in-game and of little use competitively, means that this is a virtually worthless card.
