Yes. And definitely yes. The structure decks are worthless as-is, they're just a cheap way to get all the cards.
Here's an example of a pretty standard Dragonmaid deck with all the filler cards removed. Please ignore Dark End Evaporation Dragon and Light End Sublimation Dragon. They haven't finished their maid lessons yet.
Fill it with whatever staples you have/can get. The one time bundles that give a guaranteed card in the shop are very good.

That's how the game goes. It's standard to run hand traps(cards you can use on the opponent's turn from hand) to make it harder for them to combo off.
