Ajani By Any Other Name - BRONZE
Thanks for everyone participating in this week's scenario. Peter Calomeris was first to chime in identifying a key piece of information: there is more than one Ajani in standard!
Although players are allowed to truncate names of Legendary or Planeswalker characters, they can only do so if there is only one instance of that character in the format they are playing. Ajani, however, shows up twice in Standard: once as Ajani Unyielding, and once as Ajani, Valiant Protector in the Planeswalker Deck. Therefore, Percy has committed a Deck / Decklist Problem, and receives a Game Loss.
Because this decklist error was not discovered during a deck check, the penalty should not be applied until the beginning of the next round. Wait until Percy's match is finished, then explain the penalty, and update his decklist to match his deck, being sure to check for any other errors as well. The penalty will be enforced at the start of Percy's next match.
