Hello!
Let me try to help you
I guess you're born in january, so you get creatures born in january too. If you try to propose an exchange to G.O. (the account that owe all creatures for raffles), you'll see that all creatures have the letters of a month and a number in their name. So you take all creatures who have "JAN" and the numbers 42, 65, 68 and 74, you put them in the exchange and give a creature in return (but you can give anything you want, rank 1 for example).
Is it more clear? Eliya explained
