Regarding the second question, the supposed implication for legality's sake is that she used Gate of Pardon, -Forgiven-'s ability off-screen to regain 1 life (notice the 14 to 15 jump when Tasuku heads into the kill turn - cards returned were Ultimate Buddy!, Deity of Law, and Deity Dragon Envoy, Muriel). This also applies to Guardian Deity Dragon of Paradise, Avalon's on-call effect, returning only two cards.

From what I recall, the anime sometimes leaves significant parts of the action off-screen. Since Bakunetsu Saigen! Buddyfight!! was not there beyond season 1, some legwork is required to determine what happened in regards to the real card game.
