Advice? See description.

Finally got Wemby this week, and dude is ELITE! I also have Opal Robinson and PD Kristaps (from a Challenge pack so unsellable). Obviously Wemby is better than both, but I’m MT poor after buying him. Would you sell him and run KP and The Admiral? Also what’s the best way to sell a card like this? 12 hours? 24 hours? Appreciate the help!
