IPG 3.9 Tournament Error — Insufficient Shuffling

Definition

A player unintentionally fails to sufficiently shuffle their deck or portion of their deck before presenting it to their opponent or fails to present it to their opponent for further randomization. A deck is not shuffled if the judge believes a player could know the position or distribution of one or more cards in their deck.


Examples

  • A. A player forgets to shuffle their library after searching for a card.
  • B. A player searches for a card, then gives the library a single riffle-shuffle before presenting the library to their opponent.
  • C. A player fails to shuffle the portion of their library revealed during the resolution of a cascade ability.

Philosophy

Players are expected to shuffle their deck thoroughly when it is required and are expected to have the skill and understanding of randomization to do so.

However, as the opponent has the opportunity to shuffle after the player does, the potential for advantage is lowered if tournament policy is followed.

Any time cards in a deck could be seen, including during shuffling, it is no longer shuffled, even if the player only knows the position of one or two cards. Players are expected to take care in shuffling not to reveal cards to themselves, their teammates, or their opponents.

A player should shuffle their deck using multiple methods. Patterned pile-shuffling is only allowed at the start of a game. Any manipulation, weaving, or stacking prior to randomization is acceptable, as long as the deck is thoroughly shuffled afterwards.

Any manipulation, weaving, or stacking prior to randomization is acceptable, as long as the deck is thoroughly shuffled afterwards.

Additional Remedy

Shuffle the appropriate portion of the deck thoroughly.
