From Bulbapedia, the community-driven Pokémon encyclopedia.
Legendary Ascent is the name of the deck used by Tom Roos, the Masters Division Champion in the 2007 World Championships. It is based on the Absolutions archetype that was popular during the 2006-2007 season.
Legendary Ascent is one of the four 2007 World Championships Decks, released on November 19, 2007. Each deck comes packaged with a 2007 World Championships Booklet. Each card features a silver border, Roos' signature, and limited edition 2007 World Championships back. None of the cards are tournament legal.
Tom Roos scored the win in the finals of the Masters Division to become Champion with his strategy-filled deck! Rayquaza ex was feared the entire tournament due to its powerful attacks and high HP. Special Circuit and Sky-high Claws were dangerous right from the start, becoming even more efficient if Rayquaza ex ever fell behind!
