Sapphire CollectorHow it works & interactions with other cards

Conjuring the Mox

Sapphire Collector features a unique trigger that activates when you cast your second noncreature spell in a single turn. When this condition is met, a card named Mox Sapphire is conjured directly into your hand. This is an 'Alchemy' mechanic, meaning the card is created out of thin air and becomes a permanent part of your hand or deck for the duration of the game.

Mastering the Flashback

For a cost of {2}{U}, you can target an instant or sorcery card in your graveyard to give it flashback until end of turn. The flashback cost will be exactly the mana cost of the chosen card. This allows you to reuse your best spells to trigger Prowess multiple times, or to reach that crucial second noncreature spell for the Mox trigger.

Trigger Restrictions

It is important to note that the conjuring ability triggers only once per game per Sapphire Collector. Even if you cast a fourth or sixth noncreature spell in the same turn, or wait for the next turn, you will not receive a second Mox Sapphire from the same permanent. However, the Prowess ability continues to trigger every time you cast a noncreature spell.

Interaction examples

Double the Treasure

Roaming ThroneMox Sapphire

If you control Roaming Throne with 'Human' or 'Mercenary' chosen as the type, Sapphire Collector's trigger will fire an additional time. When you cast your second noncreature spell, you will conjure two copies of Mox Sapphire into your hand instead of one.

Strategic Spell Sequencing

Solemn SimulacrumMox Sapphire

Note that Solemn Simulacrum is a creature spell. If you cast it followed by an instant, you have only cast one noncreature spell. To get the Mox Sapphire, you must cast two noncreature spells (like an Artifact and an Instant) regardless of how many creatures you cast in between.

Mana Ramp with Mox

Mox Sapphire

Once you conjure Mox Sapphire, you can play it for zero mana. Because it is an artifact, it counts as a noncreature spell. If you have a second Sapphire Collector on the field, playing the conjured Mox Sapphire could count as the first or second spell needed to trigger the new Collector's ability.
