You may not switch decks. DP-RR Format PlayTCG Start T16 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. The reason for the old format is that I want to test some of the decks in that era, as it was the season before I started play. Send me your deck lists via PM, and when pairings go out one person PM's their opponent with the link.
