I would suggest you buy the $200 of your choice on eBay paying with PayPal only. Check the completed listings to see recent prices then go to Las Vegas and have a good time doing what you want to do. The availability of $200 strikes is only valid when you are at the cage with your 20 $10 strikes in hand to trade. They usually issue 200 or less at a given time. The date and time of issue is announced in advance and the strikes are frequently gone in less than an hour or two.
