3 rulings from Wizards of the Coast
- 1 February 2009Whether Cliffrunner Behemoth has lifelink matters only when it deals damage (that is, at the point when its combat damage resolves, or at the point when a spell or ability that causes it to deal damage resolves). For example, if your only white permanent is a creature that receives lethal damage at the same time Cliffrunner Behemoth deals damage, the lifelink ability will still apply and you'll gain life.
- 1 February 2009Whether Cliffrunner Behemoth has haste matters only when attackers are declared. Once it's been declared as an attacker, it doesn't matter if it loses haste.
- 1 February 2009As long as at least one permanent you control is the specified color, the ability will "work" and grant this creature the bonus. Otherwise, it won't have the bonus.
