Magic Room is an item-disabling Psychic-type move.
Magic Room does not block the use of Mega Stones to Mega Evolve. Magic Room prohibits the use of Natural Gift and Fling, but will not suppress the effect of Berries if they were consumed through Pluck or Bug Bite.
As of 1.0.4, it can be taught by the Debuff Move Tutor in the Tsukinami Village Hotel for four Green Shards. In 1.0.3, it may be learned from the Ultimate Move Tutor in Tsukinami Village at the cost of four of each type of shard.
