Gatewatch Assembled

This card may only be cast from your hand,
using Mana generated by lands.
Search your library for a Gideon, Jace, Chandra, Liliana, or Nissa Planeswalker
and put it into the Battlefield.
If you control a Gideon, Jace, Chandra, Liliana
and Nissa Planeswalker, you win the Game.
When the Multiverse needs them most, they assemble.
