Viridian Longbow 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

Equipped creature has ": This creature deals 1 damage to any target." Equip (: Attach to target creature you control. Equip only as a sorcery.)

Complete guide

Viridian Longbow is a classic piece of equipment that transforms any creature into a repeatable source of damage. By granting a simple tap ability, it allows even the smallest utility creatures to control the board or chip away at your opponent's life total.

Sharpening the Aim

Viridian Longbow provides the equipped creature with an activated ability: '{T}: This creature deals 1 damage to any target.' It is important to note that the creature is the source of the damage, not the artifact itself. This means that if the creature has abilities like deathtouch or lifelink, they will apply to the damage dealt by this ability.

The Timing of the Hunt

To use the Longbow, you must first pay the Equip cost of {3} as a sorcery to attach it to a creature you control. Once attached, the creature must not have 'summoning sickness' to use the tap ability. If you move the Longbow to a different creature, the first creature loses the ability immediately, and the new creature gains it.

Common Strategic Errors

A common mistake is forgetting that the Equip ability can only be activated during your own main phase when the stack is empty. Additionally, players sometimes forget that if the equipped creature leaves the battlefield in response to you activating the tap ability, the ability still resolves and deals damage based on the creature's last known information.

When to Deploy the Bow

This card is most effective in decks that can produce extra mana to cover the equip cost or in strategies involving creatures with 'untap' synergies. It is a fantastic tool for picking off small creatures with 1 toughness or finishing off planeswalkers that have nearly reached their ultimate ability.

Interaction examples

Powering the Equipment

Sol Ring

You cast Viridian Longbow for {1}. You then tap Sol Ring to add {C}{C} to your mana pool. You can use this mana plus one additional mana from another source to pay the {3} Equip cost, attaching the Longbow to a creature you control. The creature can now tap to deal 1 damage.

Color Fixing for the Equip Cost

Arcane Signet

If you are short on a specific color of mana but need to equip your Viridian Longbow, you can tap Arcane Signet to produce a mana of your commander's color identity. Use this mana toward the {3} required to move the Longbow to a key blocker, allowing it to ping an attacking creature later that turn.

Standard Pinging Operation

With Viridian Longbow already equipped to a creature you have controlled since the start of your turn, you tap that creature. You choose an opponent's creature with 1 toughness as the target. The ability resolves, and the equipped creature deals 1 damage to the target, causing it to be destroyed by state-based actions.
