Robe Of The Magi

This enters the battlefield with X Slot counters.
Whenever you cast a noncreature spell, remove
a Slot counter then Scry 1 or draw a card.
When you remove the last Slot counter, this
artifact becomes a 0/0 Artifact creature with
Reach and put +1/+1 counters on it for each
Instant and Sorcery in your graveyard.
