A mana ability is an ability that (1) isn't a loyalty ability, (2) doesn't target, and (3) could put mana into a player's mana pool when it resolves.
4/15/2013
An ability that triggers when something "attacks and isn't blocked" triggers in the declare blockers step after blockers are declared if (1) that creature is attacking and (2) no creatures are declared to block it. It will trigger even if that creature was put onto the battlefield attacking rather than having been declared as an attacker in the declare attackers step.
