I've had a lot of success with this deck so I thought I'd share.
My advice would be to only play across two locations if the board allows, saving the open location for the patriot onslaught combination. I've found that the majority of times that combination plus a squirrel is enough to win that location.
If your opponent is playing aggressively across all three locations and you feel you might not win the majority of the board comfortably, you should consider using Mystique as a cheaper way of triggering patriot's ongoing effect and playing a 'no ability' card in a different location.
Key points to note:
Onslaught should be played wherever you place patriot.
Use Mystique instead of Onslaught if you're not going to win the location.
