Complete guide
Jetfire, Ingenious Scientist is a versatile Transformers card that bridges the gap between massive mana production and aerial aggression. Whether you are casting him as a robot or a high-tech vehicle, he excels at fueling your artifact-heavy strategies while maintaining a powerful presence on the board.
Dual Faces and Living Metal
Jetfire is a double-faced card featuring the More Than Meets the Eye keyword, allowing you to cast him for a reduced cost of {3}{U} directly as the Jetfire, Air Guardian vehicle. On your turn, the Living Metal ability ensures he is always an artifact creature, meaning you don't need to pay a crew cost to attack or block. Converting Jetfire is the core of his gameplay; you turn the physical card over to switch between his Scientist and Air Guardian forms while retaining all counters and attachments.
Converting for Mana and Adaptation
The transformation process works in two ways. As the Scientist, you can remove any number of +1/+1 counters from artifacts you control to target a player and give them {C} for each counter removed. This mana is restricted: you cannot use it to cast nonartifact spells, though you can use it for activated abilities or ward costs. Once this resolves, Jetfire converts into his Vehicle form. Conversely, the Air Guardian form has an activated ability for {U}{U}{U} that converts him back into the Scientist and then grants him three +1/+1 counters via the Adapt mechanic, provided he has no counters on him.
Timing and Stacking Rulings
Unlike many mana-producing cards, Jetfire's Scientist ability is not a 'mana ability' because it requires a target. This means it uses the stack and can be responded to by opponents. If the target player becomes illegal before the ability resolves, the ability fails, no mana is added, and Jetfire does not convert. Additionally, remember that while Jetfire is a creature on your turn due to Living Metal, he reverts to a noncreature artifact on your opponents' turns, which can protect him from creature-only board wipes.
Interaction examples
Solemn SimulacrumWith Jetfire, Ingenious Scientist on the battlefield and three +1/+1 counters on your artifacts, you can activate Jetfire's ability to remove all three counters. You target yourself to add {C}{C}{C}. Since Solemn Simulacrum is an artifact spell, you can use this specific mana to pay for three of its {4} mana cost, successfully casting it even with the restriction on the mana's use.
Roaming ThroneIf your opponent targets your Roaming Throne with a removal spell, you can activate Jetfire, Ingenious Scientist's ability to remove a +1/+1 counter from Roaming Throne itself. You add {C} to your mana pool. Although this mana cannot be used for nonartifact spells, the official rulings clarify it can be used for other costs. You can use this {C} to help pay for Roaming Throne's Ward {2} cost, effectively using its own counters to protect itself.

How it works : Jetfire, Ingenious Scientist // Jetfire, Air Guardian
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
Mana that you add with Jetfire, Ingenious Scientist's activated ability can be used on anything that isn't a nonartifact spell. This includes paying costs to activate abilities of both artifact and nonartifact permanents, paying ward costs, and so on.
No other card is named in this ruling.
- #2· Wizards of the Coast
Because it has a target, Jetfire, Ingenious Scientist's activated ability isn't a mana ability. It uses the stack and can be responded to.
No other card is named in this ruling.
- #3· Wizards of the Coast
The convert keyword action functions the same way as the transform keyword action found on some other cards; to convert a permanent on the battlefield, turn it over so that its other face is up.
No other card is named in this ruling.
- #4· Wizards of the Coast
The mana value of a converted permanent on the battlefield is equal to the mana value of the card's front face, no matter which face is up.
No other card is named in this ruling.
- #5· Wizards of the Coast
Converting a permanent doesn't affect any Auras or Equipment that are attached to it. Similarly, any counters on the permanent will remain on that permanent after it converts. Any continuous effects from a resolved spell or ability will continue to affect it. Any spells or abilities on the stack that target a permanent continue to do so after that permanent converts.
No other card is named in this ruling.
- #6· Wizards of the Coast
Any triggered ability of another card that triggers whenever a permanent transforms will also trigger whenever a permanent converts.
No other card is named in this ruling.
- #7· Wizards of the Coast
Similarly, an ability of another card that instructs you to "transform" one of these cards will cause you to convert it, even if that ability doesn't use the word "convert."
No other card is named in this ruling.
- #8· Wizards of the Coast
"More Than Meets the Eye [cost]" means "You may cast this card converted by paying [cost] rather than its mana cost." It functions in any zone from which the spell can be cast.
No other card is named in this ruling.
- #9· Wizards of the Coast
The cost is an alternative cost, so it can't be combined with any other alternative costs. It can be combined with any applicable additional costs.
No other card is named in this ruling.
- #10· Wizards of the Coast
When you cast a spell using its More Than Meets the Eye ability, the card is put onto the stack with its back face up. The resulting spell has all characteristics of that face.
No other card is named in this ruling.
- #11· Wizards of the Coast
To determine the total cost of a spell, start with the mana cost or alternative cost (such as a More Than Meets the Eye cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of a spell cast using More Than Meets the Eye is determined by the mana cost on the front face of the card, no matter what the total cost to cast the spell was.
No other card is named in this ruling.
- #12· Wizards of the Coast
A spell cast this way enters the battlefield with its back face up.
No other card is named in this ruling.
- #13· Wizards of the Coast
If you copy a permanent spell cast this way, the copy has the characteristics of the card's back face, even though it isn't itself a double-faced card.
No other card is named in this ruling.
- #14· Wizards of the Coast
"Living metal" means "As long as it's your turn, this permanent is an artifact creature in addition to its other types."
No other card is named in this ruling.
- #15· Wizards of the Coast
While it's a creature, the Vehicle has its printed power and toughness.
No other card is named in this ruling.
- #16· Wizards of the Coast
If a static ability of another permanent applies only to noncreature permanents, that ability applies to a Vehicle with living metal only during your opponents' turns. For example, if you control Arcee, Acrobatic Coupe and March of the Machines, Arcee will be a 2/2 artifact creature during your turn and a 3/3 artifact creature (because its mana value is 3) during each opponent's turn.
No other card is named in this ruling.
