Magic The Gathering (Magic The Gathering) #18 Cover B Secret Planeswalker Variant

Tezzeret knows he's been betrayed... and he's set his bloodhound, Tibalt, on the traitor's trail. Now Garruk, Chandra, and Niko are all that stand between Davriel Cane and a gruesome death at Tibalt's hands. But the appearance of a guest Planeswalker might just give our heroes exactly what they need to find their way back to Ravnica, and save Vraska, Kaya, and Ral!
