Have to play some weird numbers to fill in for missing cards, but it's still Swordsoul Tenyi with Protos (minus Chengying).
Put some Ice Prisons in because I have a royal one and couldn't think what else to use
After guessing 3 cards you only get Legacy Tickets and SR dust.
Rewards are: 100x gems 3x legacy tickets for the first 3 cards,
then 6x legacy tickets 10x SR dust for the last four cards.
Totalling: 300x gems, 33x legacy tickets and 40x SR dust
Maybe some old meta decks no one plays anymore in Master rank are the best decks for this, or we have to go in the tank to make something that works
