Kingdom

When Kingdom enters the battlefield, for each land you control choose one for as long as Kingdom remains on the battlefield:
-That land becomes a 2/2 white Knight creature with haste and vigilance. It's still a land.
-That land becomes a 3/1 red Warrior creature with first strike and haste. It's still a land.
-That land becomes a 1/4 green Monk with hexproof and haste. It's still a land.
The first to unravel was Kingdom, entire cities reforged into the armies of the Cycle.
