Well, i managed to get all cards (3 copies each) from Tag Duel.
I gathered a lot of Letters first and only started doing the Event in the last 3 days (collected over 1000+, so had no issue).
Used "Ra-Aroma" Deck, so it was easy to win with auto-duel (with around 80% win-rate). Was getting around 1700+ Coins from Dark Magician Cup round (didn't lose even once against Yubel lvl 50 or lower either).
