As this is a budget version (less than 1600 dust), the upgrade path is fairly straight forward.

I swapped Snake Traps with Explosive Traps and swapped Stormhammers with Kill Command.

Simply swap these back in, if you have them.

EDIT:

Realised that the cost was actually 1640, so took out a Phase Stalker and replaced it with a Netherspite Historian to bring it down to 1580. The stalker is probably better, but there are not that many secrets in the deck, and the historian gets you moar dragons!
