Uncommon Cards are more tanky than the common cards but not by much, you just need that common evolves into a uncommon then a rare. Uncommon are better than common yes but they are in between Tanky and Squishy. A regular Uncommon should have 90-100HP or 110 in rare cases. they have decent moves that do around 50-80 damage and use a little bit more energy cards to use but it's worth it if they evolve into something good!
This pokemon evolves into a really good pokemon called "Aegislash"
