Arcane Rock

Other noncreature permanents you control gain
hexproof as long as Arcane Rock is untapped.
{1}: Add one mana of any color to your mana
pool. If you control no creatures, add 3
mana of any color to your mana pool instead.
{4}{t}: Scry 7, then draw a card.
The glow captivates even the Esper mages.
