Got Bipinna Cosmos Compensation. Need some FGs to use draw 10+1.

I wanted to try my luck using single draw but I think the chances of winning 5 * or rainbow would not be very favorable to me.

If I was sure I would win at least two 5 * using single draw and 1 Rainbow would use 9 times, and each time already earned a ticket 4 * would be a great deal.
