Whenever the Ring tempts you, if you chose a creature other than Aragorn as your Ring-bearer, put your choice of a counter from among first strike, vigilance, deathtouch, and lifelink 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.
Aragorn turns the Ring temptation and any counter you place onto him into a board-wide buffing engine, copying keyword counters (and any other counters) onto a second creature each time. You curve out into proactive creatures, get tempted by the Ring early, then snowball with +1/+1 counters and counter-doublers to build a wide, evasive, keyword-stacked board that overruns the table.
Free recurring value: the Ring tempts you repeatedly, drip-feeding keyword counters every turn
Second ability triggers on ANY counters, not just keyword ones, so +1/+1 counter synergies double up
Cheap 3-mana body in GW lets you start the counter engine early and rebuild after wipes
Grants relevant evasion/keywords (lifelink, deathtouch, vigilance, first strike) that fix attacking math
Flexible host for counters, proliferate, and go-wide token strategies
The Ring temptation only adds keyword counters, not +1/+1 counters, so raw power needs outside sources
Removal-heavy tables can blow up Aragorn and stall the engine
Slower than dedicated combo decks; relies on connecting in combat
Color identity lacks card draw and interaction depth of other shards
Buffs are spread thin if you don't go wide or pick high-value targets
