Ultra Ball requires players to discard two cards to use it, but by doing so, players can add any Pokmon from their deck to their hand
Like most Pokmon cards, the value of Banette depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Lost Origin)
Kinda sad when I discovered seven of them had holofoil versions, but the Koga was only available as non-holo
Not many decks can keep pace with a 4/4 every turn for the entire game
A PSA 4 has more visible surface wear, or several light scratches, and may be more noticeably off-center
Likewise, if you fail to draw Stifle, or if Stifle gets countered, then Phyrexian Dreadnought is a very weak creature
