While that's a valid strategy if you are low on slimes, gold, or N cards, you can be a bit more efficient about it. The amount of experience given by a slime or AW is the same, regardless of the level of the target card. On the other hand the amount of gold required increases as the level of the target card increases. In addition to that, if you level the card a bit before taking it into AW fights, the card may be able to survive 2 hits from the AW instead of 3, making the fights slightly easier.
