Whenever another creature or artifact you control is put into a graveyard from the battlefield, put an oil counter on this creature.
Whenever this creature attacks, you may remove two oil counters from it. When you do, target creature can't block this turn.
You don't choose a target for Forgehammer Centurion's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you remove two oil counters this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
