don't play this, or do Delcatty can get Gigalith EX attacking on turn 3 assuming you go second, don't brick with Onix or Roggenrola in the active, don't get KO'ed early, find Brock turn 2, and don't get bench-sniped + Cyrus'ed. After that you can use Big Air Balloon to retreat into your fossil, discard it, and attack again.
