Let's start with your first sentence. Double Edge is useless? No...my fault...you THINK Double Edge is useless? Man, take it from a Gen 1 player, the more things change, the more they remain the same (I tell ya, lol). Perhaps you haven't heard OR you are choosing to ignore: Marowak doubles the base power for its attacks on its move set while holding Thick Club. You don't need to raise his attack stat with a weak Power-up Punch just to knock your opponent out with the next move anyway. Instead, cover your weakness and utilize your ability or then why even have it? You don't need two ground moves, trust me. In no scenario will you need two ground moves. Oh look, I bet a neat Double Edge will fit nicely right where you have your Earthquake. Fire Punch won't do anything that his other moves won't? Fire Punch will do more than it's other two moves will do? What? My Bellossom would be so lucky to have an appetizer such as your Marowak. Why stop there? Venusaur, Victreebel, Petilil, etc...get it? They are all of the grass type and you have nothing to stop Grass type pokemon. Fire Punch covers weaknesses and types like Grass, Bug, Steel, and Ice, not to mention it hits double hard when it comes to mix types like Bug/Steel types. Swords Dance is a set-up move. I also don't use it when it comes to Marowak, and don't think he should have it if it is holding its Thick Club, but it's not a waste. It's all about strategy when it comes to moves like that. I'm not trying to be mean or disrespectful, but I, as an advanced player, am telling you...this is a setup that is only half done.
