Note: Some cards in this tier group can be really useful in specific situations and when you build focused decks like fast, spamming deck. So still not to completely ignore them!

DR-1: I have a love-hate relationship with this card. On one hand, it's extremely good and useful, especially since it explodes into pieces, dealing DaD (damage after death). On the other hand, it's exactly this that can completely ruin your plan if you have any friendlies nearby...

Clayton Carmine: Carmine is extremely useful in specific situations. His Carnage Skill can prove deadly under the right circumstances, so definitely experiment with him a bit before deciding if he's worth it or not.

Sentinel: Any Pin that spawns with invincibility is worth looking at, and that's exactly what the Sentinel offers. Its main problem is that it is unlocked so late in the game, when you probably have better cards upgraded already...

Kantus: I really like Kantus and I am sure that with a bit of experience, you can turn him into a really useful asset: just place him behind and keep him alive for long enough to make his damage boosting ability really useful!

Gnasher Gang: A really good set of units: three of them with decent HP and dealing decent damage as well.

Grinder: A card that's difficult to play - but which, if played well, can simply wipe out all enemies on the field. It takes time for its machine gun to load up... so it's not always that useful.

Butcher: You start with this guy and quickly build him into a monster. Tons of HP, lots of damage... the Buthcer is an easy pick for rushing towards the enemy towers and destroying them.

Kait Diaz: I find her very similar to Butcher: despite having way less health, she is faster and deals the same amount of damage.

Boomer An alternative for the Savage Grenadier... but I consider him less useful because of his lower damage. He does have more health to compensate, but sometimes just a powerful grenade is what you need and Boomer doesn't offer that.

Wretches: A good troop for when you want to outnumber the enemy. They are wiped out instantly by the correct counter, though and can become potentially useless.

Snub Soldiers: Similar to the Wretches, but a bit more useful since they also capture territory. Cheap and dependable, they can be a useful addition to any deck.
