Just e few tweaks that imo helps a lot with faster decks .
Cold Blood – help with early removal (Boar, Skaterbot) and healing (Vicious Scalehide), increasing dmg in late game.
Skaterbot – Rush minion that you can stick to Annoy-o-tron.
Stonehill Defender, Tar Creeper – best taunt mobs to slow down agrro decks.
