This deck is designed around reyand's zoo, and the adaptions made to it over time. like xixo's addition of implosion and sea giant.
You want to look for Flame Imp, Voidwalker, Haunted Creeper, Knife Juggler, Dire Wolf Alpha, & Argent Squire. Other then this these cards you usually want to toss everything else.
Exceptions: Nerubian Egg against Shaman & Paladin.
