Karn's Bastion (PWAR-248, Prerelease stamp) is a Land. It taps for colorless and has an activated four-mana ability that proliferates, adding additional counters to chosen permanents and players. Official rulings note you may choose zero targets when proliferating, you can target opponents' permanents and players, and how multiple counter types like +1/+1 and −1/−1 interact.
