Minnea, Planar TouristHow it works & interactions with other cards

Choosing Your Destination

As Minnea, Planar Tourist enters the battlefield, you must choose a specific plane, such as Ravnica, Innistrad, or Mirrodin. This choice is made as part of the resolution of the creature spell, meaning it does not use the stack and cannot be responded to once the creature begins to enter. Once chosen, the discount applies immediately to all applicable spells you attempt to cast.

Defining Planar Origin

A spell is considered from the chosen plane if its identity is clear 'beyond doubt.' This can be verified through the card's name, the visual style and landmarks in the art, the flavor text, or even external lore research. Because this is a silver-bordered style effect, clear communication with your playgroup and having a source ready to prove a card's origin is key to using the discount effectively.

The Cost Reduction Mechanics

Minnea reduces the cost of spells from the chosen plane by one mana of any single color: {W}, {U}, {B}, {R}, or {G}. It is important to note that this reduction can only apply to a colored mana symbol in the spell's cost. If a spell costs only generic mana (like many artifacts), Minnea's ability will not reduce that cost unless there is a colored component to apply it to.

Interaction examples

Returning to Dominaria

Eternal Witness

If you choose Dominaria as Minnea, Planar Tourist enters the battlefield, you can use the discount on Eternal Witness, which is famously from the continent of Otaria on Dominaria. When casting Eternal Witness, you apply the reduction to one of the {G} symbols in its {1}{G}{G} cost, meaning you only pay {1}{G} to cast the spell.

The Origin of the Simulacrum

Solemn Simulacrum

If you choose Mirrodin as your plane, you might look at Solemn Simulacrum. While the original printing of Solemn Simulacrum is from the Mirrodin expansion, the spell costs {4} generic mana. Because Minnea, Planar Tourist specifically reduces costs by one colored mana ({W}, {U}, {B}, {R}, or {G}), it provides no discount for the generic mana cost of Solemn Simulacrum, even though the card is clearly from the chosen plane.
