Kami of TransmutationHow it works & interactions with other cards

What It Does

When Kami of Transmutation enters or leaves the battlefield, you choose between making all permanent cards in your hand perpetually either artifacts or enchantments. 'Perpetually' is a keyword that means the modification is permanent; it does not fall off when the card changes zones. Because this ability affects cards in your hand, it changes how those cards are classified for the rest of the game, including while they are on the stack or on the battlefield.

Step-by-Step Resolution

First, the triggered ability goes on the stack when Kami of Transmutation enters or leaves the battlefield. Second, as the ability resolves, you choose one of the two modes: artifact or enchantment. Finally, the chosen type is added to every permanent card currently in your hand. It is important to note that this effect only hits cards in your hand at the moment of resolution; cards drawn later will not have the additional type unless the ability triggers again.

Common Mistakes

A common point of confusion is how this affects non-permanent spells. The ability specifically targets 'permanent cards,' so instant and sorcery cards in your hand remain unaffected. Another mistake is assuming the effect is temporary. Because it uses the 'perpetually' mechanic, if you choose the artifact mode and then cast a creature, that creature remains an artifact on the battlefield and will trigger any 'whenever an artifact enters' abilities.

When to Play It

This card is best utilized in decks that rely on a high density of a specific card type to function. By turning your entire hand into artifacts, you can ensure your artifact-matters cards are always active. Since the ability triggers on both entering and leaving the battlefield, you can often double-dip by playing the Kami early to set up your hand, and then benefiting again if it is destroyed or bounced back to your hand.

Interaction examples

Boosting Artifact Synergy

Esper Sentinel

If you have Esper Sentinel in your hand and play Kami of Transmutation, choosing the artifact mode, Esper Sentinel remains an artifact (which it already was). However, if you had other non-artifact creatures, they would join the Sentinel in triggering artifact-related cost reductions or search effects. The Sentinel itself serves as a reminder that having multiple artifacts on the board can tax your opponent's resources effectively.

Fixing Types for Mana Dorks

Ornithopter of Paradise

When Kami of Transmutation triggers its enchantment mode, an Ornithopter of Paradise in your hand becomes an Artifact Enchantment Creature. When you cast it, it will trigger abilities that look for enchantments entering the battlefield, while still retaining its ability to fly and produce mana. This allows the Ornithopter to bridge the gap between artifact-heavy and enchantment-heavy strategies seamlessly.
