4 blue shards i think teach it to a golduck or psyduck holding the mind plate it does 100 i think !
You can trade them to the move tutors so that your Pokemon can learn different moves.
There is a move tutor west of pastoria city who will teach it to one of your Pokemon for 6 blue shards and 2 red shards ;)
