Unless you know what you're up against it's best to play turn one Fire fly or hallucination, turn two hero power, turn three Blink Fix or Hench-clan thug. Backstab and eviscerate to help remove early threats.
For aggro matchups use fire fly for early board pressence, spells for removal and Rotten Applebaum for heals and taunt.
This deck definitely needs some fine tuning but it’s pretty good so far. There’s three different win conditions depending on how the games are going.
First there’s the classic Edwin VanCleef, get him as big as possible and kill your opponent.
Second would be Fal'dorei Strider. Full the board with spiders using Auctioneer and cheap spell to draw cards.
Third you have the new card Tess Greymane who can at times be unpredictable but can pull off some crazy turns. Using Hallucination, Blink Fox and Face Collector to get creatures and spells to feed Tess.
