confirmed in the game from data mining. But probably only as event NPC cards for upcoming Battle City Tournament event that maybe similar as Duelist Kingdom.
Egyptian gods will suck honestly, way too hard to summon. You very rarely have more than 2 cards in your hand in duel links so you've essentially got 3 sacrifices for a 2000 beater at most, ra gets its attack points from your life points so max you'll get is 3900 unless you use some life points increasing cards but it'll still leave you with 100l.p., obelisk might be good but 3 tributes is a lot
