Thorin, King of Durin's Folk

Double strike, haste, unleash (You may have this
creature enter the battlefield with a +1/+1 counter on
it. It can't block as long as it has a +1/+1 counter on
it. This creature can attack and {t} as soon as it comes
under your control.)
Whenever a creature you control deals combat
damage to a player, goad each creature that
player controls. (Until your next turn, those
creatures attack each combat if able and attack a
player other than you if able.)
