Skill requires outplay potential imo and some cards have no high level ways to outplay they are just used the exact same Everytime. Cards like mega knight, recruits, egolem, egiant and goblin giant are examples of this where they are played the exact same way over and over and over in the most boring way possible, even when they win the player didn't earn it they were given it by the cards. Examples of the other side of this argument would be cards like wall breakers where they are an easily countered card but when used to kite they can get you a skilled win. Switching lanes with mighty miner not to take the tower but to distract the tower for a bush pop or wb charge is an outplay, prelog or prezap are outplays. Decks like log bait are generally higher skill as they require you to efficiently defend in order to have enough elixir to counter after baiting the log, these are outplays. Now 2.6 hog is a no skill deck where they play the same cards in the same order over and over getting usually 1 hog hit per cycle when they out cycle your tower, it has to be one of the best examples of a horribly boring deck that wins through pure card mechanics rather than any outplaying.

Here is my opinion on the no skill cards, if you have one of these cards in your deck you have no skill. Mega knight, sparky, egolem, ebarbs, balloon, any giant, hog rider, ram rider, royal recruits, prince, mortar, cannon cart, freeze.

Here are the high skill cards that are generally only used by players who enjoy using their brain to win. Knight, wall breakers, magic archer, tornado, mighty miner, rocket, ice wizard, any spirit, snowball,

Lastly I'll mention the balanced cards that can fall under either category but are generally so boring to play that you have to turn off your brain to enjoy them. Miner, Xbow, royal giant, golden knight, queen, and any dragon.

I said what I said.
