Creature - Goblin Soldier 

2/2 

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.) // At the beginning of combat on your turn, create a 1/1 red Goblin creature token. That token gains haste until end of turn and attacks this combat if able.
