Ascending the Jagged Peak

When Ascending the Jagged Peak enters and whenever you cast a spell with mana value 5 or greater, draw a card.

”Ahh, drake warrior, dear friend. Take this
finger. Scale the Jagged Peak. Face Bayle the
Dread. My limbs are limbs no more. My heart is
twice-over filled with fear. But a drake warrior
I remain.”—Drake Warrior Igon
