Miraging Metamorph (Red)

Phantasm

When this is destroyed, create a token copy of an aura you control.

Rulings

Auras stay in the arena until they are destroyed.
The token can be represented by a small object such as a card sleeve, coin, dice or anything that is clear to your opponent.
An attack action card that is put into the graveyard from the combat chain is not considered to be destroyed.
A copy has the same parameters, and copyable (printed) properties, as that object it is a copy of. It does not copy any counters on, or effects specific to, the copied object.

Keyword notes

Phantasm - Phantasm is a new keyword that exists on Illusionist attacks. Illusionist attacks with phantasm are powerful but fragile. When an attack with phantasm is defended by a 6{p}+ non-Illusionist attack action card, the attack is destroyed and the combat chain closes.

If an attack action is destroyed, it does not resolve. Hit triggers and effects that require the action resolving such as go again do not resolve.
Both players have priority during the defending step. Note: This is a new rule introduced with the release of Monarch.
When an attack with phantasm is defended by a 6+ non-Illusionist attack action, a trigger to destroy the attack is put on the chain. Players can respond to this. When it resolves it checks if the attack action still fulfills the requirements to destroy the attack.
Phantasm only triggers when the game state changes from false to true. It does not trigger from true to true. (For example: if a defending card goes from 5 to 6 it will create a trigger, but a card going from 6 to 7 will not create another trigger.)
