Order deception plays best as an aggro deck. You've got a mix of aggressive and control cards, which generally leads to poor performance. Start by dropping the following:

- Polyhymnia
- Ransom
- Ring of the Siren (drop at least 1)
- Golden Curse
- Demolitions Expert
- Pray to Win

Replace them with solid cards like

- Skeleton Heavy
- Armor Lurker
- Axewoman

If you try to go too heavy on a theme (aka order), you'll likely gimp your deck.
