Hi Everyone,

Want to posit a policy question that has been floating around the Oceanic Judge Slack. 

Anna is playing an Izzet (B/R) deck in a local Regional Championship Qualifier.
During a deck check, you discover a forest in the deckbox which does not appear on the deck list. You note that while all cards in the deck are Blue/Red, they are playing a [[Vibrance]]

What is the penalty?

Some answers to common questions:

• The sideboard and deck had the normal 60/15, the Forest was the 16th card in the sideboard
• The deck has no other way of generating Green mana, or untapping lands. So even with the forest, they cannot generate GG for Vibrancy.
• The Sideboard was not presented prior to the Game or Match
• Anna says that the Forest came from a Draft they played earlier in the day, which they used the same sleeves for
