Has anyone solved the "My deck did it's thing and now I want a new one" problem?

After 5 or so games of my deck doing the thing, I grow bored with it always start looking for new decks to build. I am trying to get more creative with my deckbuilding, adding more and more interaction and it's helping...some. Those of you who have gotten over this, how did you do it? Do you finally find the right deck or maybe have a change in mindset?
