Hellraiser Goblin
Creature — Goblin Berserker
Creatures you control have haste and attack each combat if able.
Don't let him lead the soldiers, but by all means let him lead the way.

Hellraiser Goblin's ability also affects itself. If it enters before combat, it will have to attack that combat if able.

If, during your declare attackers step, a creature you control is tapped or is affected by a spell or ability that says it can't attack, then it doesn't attack. If there's a cost associated with having a creature attack, you aren't forced to pay that cost, so it doesn't have to attack in that case either.
