Kabutops evoultion line may not be the best, but Kabutops can really
dish out the damage and remove damage from him self at the same time.

Here's what the line looks like:

    You start out with the measly mysterious fossil.With only 10HP you
and no attacks you want to keep it in your hand until you get kabuto.

Kabuto may seem like a weak pokemon(30HP) with no chance of surving ,but
his pokemon power armor may help you keep him alive until you get
Kabutops.
You can thow in ten damage with his scracth(one colorless energy)while
you waiting also.

Finally!You pull that Kabutops from your deck.Lets take a look:

With 60HP for a thrid stage pokemon he doesn't seem as great for a
fighting deck as Machamp.His second attack makes up for that.Absorb
deals out 40 damage while it removes damage equal to half on the
defending pokemon(4 fighting energy).His first attack comes out quicker.
Sharp Sickle deals 30 damage for 2 fighting energy.To finish him up he
only has one retreat cost when many fighting pokemon have three.He is
worth putting into any fighting deck.If don't like the idea of having a
bunch of mysterious fossils in your deck just for him add a Aerodactyle,
which also is a great card and evovles from mysterious fossil.
