Armor, Dead or Alive

Backup 1 (When this creature enters the battlefield, 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.
(Equipments, Auras you control, and counters are modifications.)
