Try and draw defensive sites early. Start defensively and build mana, then switch to a semi-aggro attack. Should operate comfortably enough with a 6-8 mana top out

Common Sense draws almost anything in the deck and sets you up for most offensive or defensive situations

Early and often removal with cheap Lethals that can also be recycled using Miracle Workers mid-late game

Bury, Drown and Dispel for Cores and other annoying minions, artifacts and auras

Firebolts, Lightning Bolt and Heat Ray for mild instant damage

Cavalry for late help that can tandem w/ the Workers

Amazon Warriors and a Hydra for late-game heavies

App Wiz(+Workers) and Primordial Spring for card draw.

Mad Dash Blink and for cantrips.

A weakness might be Airborne or Void decks, which Root Spider helps a little with
