One with the Stars : règles, fonctionnement et interactions (MTG)

One with the Stars is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Enchant creature or enchantment Enchanted permanent is an enchantment and loses all other card types. (It still has its abilities, but it's no longer a creature.)

Complete guide

One with the Stars is a fascinating blue Aura that offers a unique way to neutralize threats by turning them into celestial enchantments. By stripping a permanent of its creature status, you can effectively remove it from combat without ever leaving the battlefield. This card is perfect for players who want to manipulate the very essence of their opponents' cards.

What It Does

When you attach One with the Stars to a creature or an enchantment, that permanent becomes an enchantment and loses all other card types. If it was a creature, it is no longer a creature and cannot attack, block, or be targeted by spells that only target creatures. Crucially, the permanent retains all of its original abilities, even though it can no longer participate in combat.

Resolution Step-by-Step

First, you cast One with the Stars by paying three mana and one blue mana, targeting a creature or enchantment. Upon resolution, the Aura attaches to the target. Immediately, the game checks card types; the enchanted permanent loses types like 'Creature' or 'Artifact' but keeps supertypes like 'Legendary.' Because it is no longer a creature, it no longer has power or toughness, and any equipment attached to it will fall off.

Common Mistakes

A common misconception is that the enchanted permanent loses its abilities; it does not. If you enchant a creature with a powerful triggered ability, that ability will still function. Another mistake involves power and toughness; if an ability on the card refers to its power or toughness while it is 'One with the Stars,' the game treats those values as 0. Finally, note that if the target was already just an enchantment, this card has no effect on its types.

When to Play It

This card is best used as a form of pseudo-removal against aggressive decks. By turning a massive attacker into a harmless enchantment, you negate its ability to deal combat damage while bypassing 'indestructible' or 'dies' triggers. It is also an excellent tool for protecting your own valuable creatures from creature-specific board wipes like Wrath of God.

Interaction examples

Static Taxing Effects

Propaganda

If you cast One with the Stars on an opponent's creature, they can no longer attack you with it. However, if that creature already had a tax effect like Propaganda (via a card like Opalescence turning it into a creature), the tax effect remains active because the permanent keeps its abilities.

Triggered Abilities in the Stars

Rhystic Study

If Rhystic Study has been turned into a creature by another effect and you cast One with the Stars on it, the Rhystic Study becomes just an enchantment again. The ability 'Whenever an opponent casts a spell, you may draw a card unless that player pays {1}' remains fully functional, as One with the Stars does not remove text or abilities.
