You can win Collectors worth more than 200k (I think the lowest they had was 400k)
You go into the my tickets tap under the current draw tab.
Click on the ones that you have. (Remember that you don't have to spend all of them in the same draw)
If you don't have then you could sell cards to Kate or win them via Missions.
The lottery/ prize draw is in the home page on the left under the thing with you level money and credits
