Hey, welcome back!
Several years ago, Redemption had its first set rotation. Cards from the era you played in are no longer tournament legal (aside from doing a "classic" booster draft).
Fortunately there are tons of resources available to get you caught up in terms of rules, deck strategies and obtaining cards from the most recent sets.
There is an official Redemption Discord as well as community driven sites like Landofredemption.com and YourTurnGames.biz.
I will post a message on the Discord and see if one of the moderators can send you an invite link. It would be awesome to have you at a Minnesota tournament at some point, if you'd like to be on the email list, let me know
