Mirror-Style Master

Backup 1 (When this creature enters, put a +1/+1 counter on target creature. If that's another creature, it gains the following ability until end of turn.)
Whenever this creature attacks, for each attacking modified creature you control, create a tapped and attacking token that's a copy of that creature. Exile those tokens at end of combat. (Equipment, Auras you control, and counters are modifications.)

Hilfestellung 1
Immer wenn diese Kreatur angreift, erzeuge für jede angreifende modifizierte Kreatur, die du kontrollierst, einen getappten und angreifenden Spielstein, der eine Kopie jener Kreatur ist. Schicke jene Spielsteine am Ende des Kampfes ins Exil.
