Complete guide

Jacob Hauken, Inspector is a versatile legendary creature that offers card selection in the early game before transforming into a powerful enchantment. Once he becomes Hauken's Insight, he allows you to cast massive spells for free every turn. This dual-sided card rewards careful planning and mana management.

Investigating with Jacob

While on his front side, Jacob Hauken, Inspector has a tap ability that lets you draw a card and then exile a card from your hand face down. You are allowed to look at these face-down cards at any time. During the resolution of this ability, you have the option to pay six mana to transform him into Hauken's Insight. Crucially, you draw and exile before deciding whether to pay the transformation cost.

Unlocking Hauken's Insight

Once transformed, the enchantment exiles the top card of your library at every upkeep. The most powerful feature is the ability to play one land or cast one spell from the exiled pile for free each turn. This includes cards exiled by the front side of the card before it transformed. Note that you must still follow all normal timing restrictions for the card types you are playing.

Strategic Considerations

A common mistake is forgetting that Hauken's Insight is a new object if it leaves and returns to the battlefield. If the enchantment is destroyed or bounced, any cards currently in exile remain there, but you lose the ability to play them even if you play a second copy of Jacob Hauken. Always ensure you have a legal timing window to play your free spells, especially sorceries and creatures.

Interaction examples

Building your Mana Base

Ornithopter of Paradise

You activate Jacob Hauken, Inspector, drawing a card and exiling Ornithopter of Paradise. Later, you pay the transformation cost. During your next turn, you use the 'once during each of your turns' ability of Hauken's Insight to cast the Ornithopter of Paradise for free, giving you a flying blocker and mana acceleration without spending any resources.

Cost Reduction and Free Spells

Foundry Inspector

You have Foundry Inspector on the battlefield and use Hauken's Insight to cast an artifact spell from exile. Since Hauken's Insight lets you cast the spell 'without paying its mana cost,' the cost reduction from Foundry Inspector does not change the price—it is already zero. However, this still counts as your one free spell for the turn.
