Whenever
the Ring tempts you, if you chose a creature other than Aragorn, Company Leader as your Ring-bearer, put your choice of a counter from among
first strike (This creature deals combat damage before creatures without first strike.),
vigilance (Attacking doesn't cause this creature to tap.),
deathtouch (Any amount of damage this deals to a creature is enough to destroy it.), and
lifelink (Damage dealt by the creature also causes its controller to gain that much life.) on Aragorn.
Whenever you put one or more counters on Aragorn, put one of each of those kinds of counters on up to one other target creature.
