A-Base Camp

Not yet bracketed (or genuinely unplaceable).

A-Base Camp is a colorless land that taps for {C} freely, or for any color specifically to cast/activate Clerics, Rogues, Warriors, or Wizards. A solid mana-fixing land in Brawl decks built around those four class types, most famously the Zendikar Rising party-themed archetypes. Its restricted colored mana makes it near-dead in decks that don't feature a critical mass of those creature types.
