I just played Faceless Rager in arena to play around Mirror Entity but when it triggered, the mage got a copy of my Faceless Rager and not a 5/1. This can't be intended, right? Faceless Rager's effect is a Battlecry and the text on Mirror Entity clearly reads "after your opponent plays a minion". Meaning the secret should trigger first, and the Battlecry afterwards. 

Battlecries resolve before anything else. 

The wiki says the following:

Like the other Secrets that trigger when your opponent plays a minion from their hand (Repentance, Snipe, Sacred Trial), Mirror Entity triggers in the After Play Phase following the Battlecry Phase. This means that all effects and death processing related to the minion's Battlecry resolve before the game queues and resolves Secrets such as Mirror Entity.

• Mirror Entity, Sacred Trial, Snipe, Repentance and Potion of Polymorph all trigger in order of play.
• Mirror Entity does not trigger if the minion is mortally wounded (such as by Snipe), pending destroy (such as by sacred trial) or already dead and removed from play (for example by using Injured Blademaster + Brann Bronzebeard).

The Faceless Rager was copied after the battlecry took place, and thus it will have the same buff. 

Yeah never mind lol I completely forgot that Battlecry triggers first, I haven't played in a really long time. Thanks for clearing that up.
