Artifact

Artifacts are one of the three possible Card Types.

Artifacts are a bit more protected than creatures because they cannot suffer damage and can be harder to target (but can still be destroyed by your opponents effects or sacrificed by you).

Unlike Spell cards or Instants on other games, and very much like any other card in this game, unless otherwise stated, Artifacts remain on the field until they are destroyed by some effect; while some artifacts have continuous effects, activation effects, or triggers that can happen many times, others have one-of effects and essentially lock your zones (such as Scrolls), but can still used for sacrifice fodder.

There are a few sub-types of Artifacts with special rules:

Equipment

Equipments are artifacts that can be Attached to creature imbuing them with transferable properties (Might, Life, and up to one effect).

Every Equipment has the action Equip:

Equip: Attach [this] to target creature.

Once attached, an Equipment is no longer considered a separate card, and:

• cannot be targeted (but can be chosen if an effect specifies it);
• cannot have counters of any kind (damage, mana, conditions);
• cannot be unattached naturally (though effects might allow it).

When a card is destroyed, all attached cards are destroyed with it. Attachments can also be directly destroyed by certain card effects.

Scroll

Scrolls have a powerful, one-off, "When summoned:" trigger effect, and then are essentially clutter until they can be destroyed.

They have a special rule regarding their Will: unlike other cards, they do not acquire Mana counters when summoned; in fact their "mana" is considered "spent" when their effect activates. However, their can still be sac'ed face-down for their Mana cost via the Hidden Sacrifice rule, before they are ever flipped.
