Nanotyrannus

A small theropod, once thought to be a juvenile Tyrannosaurus, that was made by DinoFlame.

Tiny Tyrant
This card is unaffected by the abilities of carnivorous dinosaurs.

Fast Fangs
This attack can be used twice per turn. Deals 70 damage.

Using Nanotyrannus
Nanotyrannus, having a fair amount of health, is a good card to have if you are battling other Lightning-attributed cards. Being able to use Fast Fangs twice, it would be a good card to have in a double battle, or simply just to deal a lot of damage to one card in one turn. Its ability is also particularly useful for taking out many Fire-attributed cards, most of which are theropods.

Defending against Nanotyrannus
It's fairly easy to defend against it. All you would need is an Earth-attributed card that deals at least 30 damage or a card that can deal at least 60 damage. With resistance cutting its attack damage in half, and often wielding damage-reducing abilities, an Earth-attributed card is often the best strategy against this card. If you have no Earth cards, then a Herrerasaurus will do just fine.
