Monk: Has to at least be level 5, to deal with shield maiden and other tanks, and to be able to silence clash abilities. His boast is not very important, but it is good to have so you can activate his super much more often.

Mega Knight: Get earthquake in later rounds, only if needed. Other than that, he is only used for being a tank. If you have enough elixir, then you could also get dark armor.

Barbarian: In some situations, you will want to use the barbarian’s first or third star ability to A, help the magic archer or B, just be able to destroy beefy opponents such as mega knight. His third star is probably more important because you really want to get the magic archer up and going.

Magic Archer: You will want to max this guy out, because he is your main carry and he is just really good. The best order in my opinion is 1st star, then 2nd star, then 3rd star. He is your main troop that you want to upgrade, and you cannot ply this deck without maxing him out. I recommend getting steel tips first, because it can really help you deal with troops such as the witch.

Miner: This guy is just used to deal extra damage to the opponents so you can get good hits off of them while they are dealing with your mega knight. You may want to get backstab or cleave, depending on the situation. If you are facing the monk, then you should use drain so he cannot activate his super very often.

Spear goblin: The spear goblin is mostly used for his clash ability at the start, so you can get his first star. But if you do not think you will have enough elixir, then you may not want to upgrade him. He can be replaced with the bowler, I would just rather have him, solely because he is cheaper.
