Tidal VisionaryHow it works & interactions with other cards

What It Does

Tidal Visionary has a single activated ability that costs no mana—only tapping the creature. When you activate this ability, you choose a target creature and a color (white, blue, black, red, or green). The target creature loses its previous colors and becomes only the color you chose until the end of the current turn.

Resolving the Ability Step by Step

First, you activate the ability by tapping Tidal Visionary and announcing your target creature. You do not choose the color until the ability actually resolves. Once the ability resolves, the creature's color is overwritten. This effect lasts until the 'cleanup step' at the end of the turn. Note that if the creature was multi-colored, it becomes a single color; if it was colorless, it gains the chosen color.

Common Mistakes

A frequent error is assuming that changing a creature's color changes its mana cost or its identity for Commander rules; it does not. Another mistake is trying to name 'colorless' as the color. Colorless is not a color in Magic: The Gathering. You must choose from the five standard colors. Finally, remember that this effect does not remove other types, like 'Artifact' or 'Merfolk'; it only changes the color attribute.

When to Play It

Tidal Visionary is best used reactively or as a setup tool. You can use it to help a creature bypass 'Protection from Blue' by changing the attacker to Red, or use it to make an opponent's creature susceptible to a spell that only targets specific colors. It is a versatile tool for decks that care about color-based interactions.

Interaction examples

Coloring the Colorless Thopter

Ornithopter of Paradise

Ornithopter of Paradise is naturally a colorless artifact creature. If you tap Tidal Visionary and choose 'Blue', the Ornithopter becomes a Blue Artifact Creature until end of turn. This allows it to be targeted by spells that require a blue target or benefit from 'blue creatures you control' effects.

Shifting the Faerie's Hue

Faerie Mastermind

Faerie Mastermind is a Blue creature. If you use Tidal Visionary to change it to Green, it stops being Blue and becomes Green. If an opponent has a spell that says 'Destroy target blue creature,' they can no longer target the Faerie Mastermind in response to your color-shift resolution.
