Purpose of the deck:
Being durable and thus outlasting your enemy

Why these cards?
Katrina: for her artifact slots + command 3 on Darius and Stonefist (and Valenti)
Flyers: Can only be hit by mages and archers, so they're pretty good tanks + they'll take out enemy flyers
Icebolt: Also meant as a counter for enemy fliers + the ability to make your opponents card lose a turn
Trap: Immobilizes your enemy while you chip their health away
Block: Makes 1 dmg units useless and adds durability to your units
Artifacts: lower ready than a normal healer
Rush: The more cards you have on the field, the more trap and freeze opportunities you get
Zap: Another way to make up for the lack of archers: against flying
Harrass: Less cards on his side means more damage to his morale
Earthworks: This will make any Infantry unit you have on the field (apart from the trappers) survive an attack from a regular archer. Also makes a nice tank thanks to its immunity

Best rating with this deck so far: 1990
Best prestation in T1-T4 tournies: 1st place

Downside of the deck: a bad pull can get your ass whooped pretty hard
