Happy Holidays @gonlid!!!
Great strategy! To be honest, I never really thought about renting cards to try decks out. I've always rented for end of season rewards or to help my current decks. Which I guess is a form of what you're doing. Also, probably means I've purchased cards I'll never use 😑.
In regards to the Chaos Dragon, unfortunately, you don't qualify per my rules listed above.
Rule 4 is a continuation of Rule 2 in that I will check comment history to verify one has been semi-active. Rule 4 says the comment has to have been made prior to me posting this blog post. At the time of my response, it shows that your first comment was made 1 day ago and my post was made 2 days ago. However, stick around because I have something up my sleeve. 🤫
I want to be as fair as possible to those that have been active on the website and incentivise those that are new to get involved here. It will only benefit you anyway.
Cheers!
