Hi,
Win Club would be my choice too. Its brandable enough and generic enough to fit both sports and casino, whether there was a football player on the page or a roulette wheel; it fits either thus leaving a lot of room for landing pages.
I definitely would not go with play2deal, or whatever that was close to reminding people of bethedealer.
Nothing against them. but I would not want to be mistaken for them either. If I were shooting for that kind of angle, I’d choose something like WilHill or innercasino
