Have you ever signed in to Steemmonsters (Now Splinterlands)?
To see if you have that Alpha pack Sign in (My affiliate link: https://steemmonsters.com?ref=rentmoney) and at the top corner of the screen you will see a "swirl" that says open when you hover over it. Click that and it will take you to the place that displays how many booster packs you have. You never know its possible that the Alpha pack you won is sitting in your account. I can't see if you own a pack but I do see that you do own a BETA Giant Roc.
If you decide you want to play the game let me know as I have an abundance of cards (BETA Mostly) and I can delegate you some for a period of time to help you get started.
Thanks for the link to your post.
Wow! I was wondering if I would ever claim that prize. It would be hilarious if it was sitting there all this time.
Thanks I will try that and also send you a tip.
