Echoing Assault

Rulings

Although the token enters attacking, it was never declared as an attacking creature. Abilities that trigger whenever a creature attacks won't trigger when that creature enters attacking. — Any "enters" abilities of the copied creature will trigger when the token enters. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied creature will also work. — If you attack multiple players in the same declare attackers step, Echoing Assault's last ability triggers once for each player you attacked. — In the case where the target creature is copying something else when Echoing Assault's second ability resolves, then the token enters as whatever that creature copied, except it's a 1/1. — The token copies exactly what was printed on the original creature and nothing else, except it's a 1/1 (unless that creature is copying something else; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its types, color, or so on.
