Grievous has 10. The Wookie Warrior has 14.
Grievous articulation is in his mid-chest, neck, arms, elbows, legs, and knees. In other words he has pretty standard articualtion. He is about on the same quality level of most Saga '04 figures. He also has a cape which the Basic one wont, a gun, and a lightsaber.
The Wookie Warrior has articulation in his neck, mid-chest, lower-chest, arms, elbows, wrists, legs, and knees. This figure is almost on VOTC quality level but not quite there. He also comes with a cool gun, and some armor.
I will also note that none of these figures have a base. And, I forgot to mention that these cards CANNOT fit in a Star Case.
