Dormant Skerry
Land (Rare)

Dormant Skerry enters the battlefield tapped unless you control two or more creatures.

Tap: Add R to your mana pool. Activate this ability only if you control a Mountain.

Tap: Add U to your mana pool. Activate this ability only if you control an Island.

1R: Dormant Skerry becomes a 1/1 blue and red Orc creature with first strike until end of turn. It's still a land.
