An attack-proxy exists as long as its attack-source exists, and as long as the attack-source is on the same chain link (if the attack-proxy is on the combat chain). If an attack-proxy is on the stack and the attack-source ceases to exist, or an attack-proxy is on the combat chain and the attack-source is not on the same chain link, the attack-proxy ceases to exist. An attack-proxy is not dependent on its attack-source having the {p} property, or the ability that created the attack-proxy.

Example: If a player attacks with a weapon, they create an attack-proxy, and the attack-proxy and the weapon (the attack-source) move to chain link 1. If the player attacks again with the same weapon during the same combat chain, a second attack-proxy is created, that attack-proxy and the weapon (on chain link 1) move to chain link 2, and the first attack-proxy ceases to exist. Last known information is used for the first attack-proxy and chain link 1.

Example: Iris of Reality has the text ”. . . Illusionist auras you control are weapons with 4 base {p} and “Once per Turn Action – {r}{r}{r}: Attack. Go again”.” If an Illusionist aura creates an attack-proxy with this ability, then Iris of Reality ceases to exist, the attack-proxy does not cease to exist.
