Welcome!! :D (This is my attempt at a quick explanation, but anyone else feel free to chime in!) Every new release, each player can claim freebies:
You may claim 10 character cards and one special from the newly released decks above. They must all be from different decks! Comment with what you take. You may also take one copy of your signature.
rg/regular - these are standard character cards. This release has 92 character decks, from which you can pick 10 cards. sp/special - this release has 4 special decks, and you can pick 1 card. sig /signature - this is 1 copy of your personal player signature card. (in my case, sig_ange) You can find more info about signature cards here
