Deck's you've played that you reccomend
Deck of choice for me season 1 was the Aggro spell mage
Deck, it uses 20 spells, the remaining minions either draw cards or buff/get buffed by spell use.
It's strong against most decks but can be countered by late game druid/pala running lots of heals or very aggro warlock/rogue who have good openers.
The general style is to go straight for face with any direct damage spell whislt using the minions and nova/blizzard to delay/stall.
If you get to turn 6 for a blizzard against lock/rogue you should be good to go, assuming you're not at single didgit hp already. Since blizzard will wipe his board. Against druid you need to stall for long enough that he uses his Ancients for card draw rather than heals, then you go for face.
The best opener is usually going second and playing Mana wyrm, coin, mirror image. Save frost bolts for use in combo with icelance if at all possible. However when picking your starting cards mulliganing anyhting that doesn't give card draw is generally best.
Turn 6 Sorc Apprentice > Ice block/Nova > Arcane intellect is very strong
Turn 7 Sorc Apprentice > Frost bolt > Frost Bolt > Ice Lance > Ice Lance > fireball is mega damage.
Coldlight oracles can be a bit dicey, but sometimes you just need that card draw. Try to not use them against locks since it's nice to have them tap their life away.
