You don't need a starter pack to play on .club. You and all of your friends can play without paying anything. STEEM is sent to your wallet after every battle. That's why we ask for at least a summoner and a monster.

They have a starter pack, and also a booster pack, and they still can't queue at steemmonsters.club.. Please re-read my post to find out why.
