Groudon, Primordial Earth

Drought — When Groudon, Primordial Earth
enters the battlefield, the sun shines bright.
(Sunny is a weather effect. Weather effects last until
the next turn of the player who placed the weather
effect or until another weather effect is placed on the battlefield.)
Landfall — Whenever a land enters the
battlefield under your control, Groudon deals 4
damage to target creature. If that land was a mountain, Groudon deals 4 damage to any target instead.
