Aragorn, the UniterHow it works & interactions with other cards

A Master of Multi-Color Synergies

Aragorn, the Uniter has four distinct triggered abilities that respond to casting spells of specific colors: white, blue, red, and green. It is important to note that these are 'on-cast' triggers, meaning they resolve before the spell that triggered them even hits the battlefield. If you cast a multicolored spell, such as a Red and Green spell, both corresponding abilities will trigger simultaneously, allowing you to choose the order they are placed on the stack.

Navigating the Stack

When you cast a spell, Aragorn's relevant abilities are placed on the stack on top of that spell. If multiple abilities trigger at once, you—the controller—decide their relative order. The last ability you put on the stack will be the first to resolve. For example, if you cast a spell that triggers both the Blue scry and the White token creation, you can choose to scry 2 first to potentially influence your future draws, or create the 1/1 Human Soldier first.

Targeting and Timing

Both the Red (damage) and Green (+4/+4) abilities require targets. You must choose a legal target opponent for the damage and a legal target creature for the buff at the moment the ability is put on the stack. If the target becomes illegal before the ability resolves (for instance, if the creature gains Hexproof or leaves the battlefield), that specific ability will fail to resolve, but the original spell you cast will still proceed as normal.

When to Lead the Charge

Aragorn is most effective when you have a hand full of cheap, multicolored spells to maximize the number of triggers per turn. Because the Green ability provides a massive +4/+4 boost, he is excellent for mid-combat surprises or pushing through lethal damage. Use the Blue scry ability early in your turn to set up your subsequent draws and ensure you hit the specific colors needed to keep the momentum going.

Interaction examples

Strengthening the Ranks

Aragorn, the UniterEternal Witness

When you cast Eternal Witness while Aragorn is on the battlefield, his Green ability triggers because Eternal Witness is a green spell. You choose a target creature to receive +4/+4. This trigger resolves before Eternal Witness enters the battlefield. Once the Witness itself resolves and enters, you then use its own ability to return a card from your graveyard to your hand.

Colorless Limitations

Aragorn, the UniterSolemn Simulacrum

If you cast Solemn Simulacrum, no abilities from Aragorn, the Uniter will trigger. Even though Solemn Simulacrum is a creature, it is colorless. Aragorn only checks for the colors White, Blue, Red, or Green; colorless spells do not satisfy any of his four conditions.

Creating the Vanguard

Aragorn, the UniterHuman Soldier

Whenever you cast any spell that contains White in its mana cost, Aragorn's first ability triggers. Before your White spell resolves, you create a 1/1 white Human Soldier creature token. This token is a separate permanent and does not benefit from the spell that created it unless that spell specifically affects creatures on the battlefield.
