Aragorn and Arwen, Wed is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Vigilance Whenever Aragorn and Arwen enters or attacks, put a +1/+1 counter on each other creature you control. You gain 1 life for each other creature you control.

Complete guide

Aragorn and Arwen, Wed is a powerful Selesnya legendary creature that celebrates the union of Gondor and Rivendell by bolstering your entire board. This card functions as both a massive anthem effect and a significant source of life gain, rewarding players who focus on building a wide presence of creatures. Whether entering the battlefield for the first time or leading the charge in combat, this duo ensures your army grows stronger and your life total stays high.

A Royal Welcome and Charge

Aragorn and Arwen, Wed features a triggered ability that activates at two distinct moments: when the card enters the battlefield and whenever it attacks. Because it has Vigilance, you can attack to trigger the ability without worrying about leaving yourself defenseless. The ability checks the number of 'other' creatures you control at the time it resolves to determine how many +1/+1 counters to distribute and how much life you gain.

Step-by-Step Resolution

When the trigger condition is met, the ability is put on the stack. Upon resolution, two things happen simultaneously: first, every creature you control except for Aragorn and Arwen, Wed receives one +1/+1 counter. Second, you calculate the total number of other creatures you control and gain that much life. If a creature leaves the battlefield in response to the trigger, it will not receive a counter and will not be counted for the life gain calculation.

Strategic Timing

To maximize the value of this card, you should aim to cast it when your board is already populated with smaller creatures or tokens. Since the ability triggers on entry, it provides an immediate impact that can turn a board of small tokens into a lethal threat. It is also highly effective in formats where you can grant it Haste or extra combat phases to repeat the buffing process multiple times in a single turn.

Common Pitfalls

A common mistake is forgetting that Aragorn and Arwen, Wed does not put a counter on itself. Only 'other' creatures receive the bonus. Additionally, the life gain is tied to the number of creatures you control as the ability resolves, not when it triggers. If an opponent casts a board wipe in response to the trigger, you may end up gaining zero life and placing zero counters if no other creatures remain.

Interaction examples

Building an Instant Army

Avenger of Zendikar

If you control Avenger of Zendikar and seven Plant tokens, casting Aragorn and Arwen, Wed will trigger its entry ability. When it resolves, the Avenger and all seven tokens each get a +1/+1 counter, and you gain 8 life. The Plants become 1/2 creatures immediately, and you can follow up with a land drop to make them even larger.

Defensive Reinforcements

Seedborn Muse

With Seedborn Muse on the battlefield, all your permanents (including Aragorn and Arwen, Wed) untap during every opponent's turn. Because the Wed duo has Vigilance, you can attack on your turn to get the counters and life gain, and still have a buffed Seedborn Muse ready to block, while also ensuring your lands are ready for interaction.
