Magic #18

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!
