Jhoira's FamiliarHow it works & interactions with other cards

Defining Historic Spells

The core of Jhoira's Familiar lies in the definition of 'historic.' A spell is considered historic if it possesses the legendary supertype, the artifact card type, or the Saga enchantment subtype. Whether a card has one of these traits or multiple—like a legendary artifact—it is simply 'historic' and receives a flat {1} cost reduction.

How the Reduction Applies

When you cast a historic spell, you follow a specific sequence: first, you announce the spell and its targets; second, you determine the total cost by starting with the mana cost or alternative cost, adding any increases, and then applying cost reductions like the one from Jhoira's Familiar. Only after these steps do you pay the final amount. Note that the Familiar cannot reduce its own cost while you are casting it, as it must already be on the battlefield for its ability to function.

Strategic Timing

To maximize the value of this Bird, you should aim to play it before your major historic threats. Since its ability is static, it provides an immediate discount to every eligible spell you cast for the rest of its duration on the battlefield. Because it has Flying, it also serves as a reliable evasive attacker or blocker while you wait to cast your more expensive spells.

Common Misconceptions

A common mistake is assuming that a card with two historic qualities, such as a Legendary Artifact, would cost {2} less. However, the game only checks if the spell is historic or not; it does not count the number of historic traits. Additionally, remember that this ability only reduces the generic mana component of a spell's cost, not colored mana requirements.

Interaction examples

Deploying Artifact Scouts

Solemn Simulacrum

With Jhoira's Familiar on the battlefield, Solemn Simulacrum is identified as an artifact spell. When you cast it, the cost reduction applies, allowing you to play the Golem for only {3} mana instead of {4}. You still get to search for a basic land and draw a card when it eventually leaves the battlefield.

Doubling Down on Golems

Roaming Throne

Roaming Throne is an artifact creature, making it a historic spell. Jhoira's Familiar reduces its cost to {3} mana. Once Roaming Throne enters the battlefield, you can choose 'Bird' as the creature type. If a future historic card triggers an ability of Jhoira's Familiar, the Throne would cause it to trigger twice, though in this specific case, the Familiar has only static and keyword abilities.
