War has come to Ravnica, and Planeswalkers from around the Multiverse are converging to fight for and against Nicol Bolas as he attempts to restore his own god-like power at the expense of countless lives.

Alongside the rest of the Gatewatch and dozens of other Planeswalkers, Jace and Gideon must hold back the tide of Eternals and prevent absolute calamity.
