The deck starts by casting efficiently costed creatures with strong secondary abilities including Claim Jumper (land fetch), Finneas (+1/+1 counters, draw), Ghired (creates tokens), Jacked Rabbit (rabbit creature tokens), Mirror Entity (increases base power/toughness), Warren Warleader (rabbit tokens, anthem effect), etc
