Otherland Mercenaries

Whenever a land enters the battlefield, its controller may tap that land and pay {1}. If he or she does, that player gains control of Otherland Mercenaries.
Even if the fungal societies of the otherland aren't as vast as those established by humans, the same basic principals of daily life still are present. For example, there are many who are willing to lend their 'services' to anyone who can pay the right price.
