Nope, they're the same as always. I honestly think that they might be even better. I already got 6+ copies of all the UR and SR cards. And I only use an Auto-Duel deck.
my drop rate is decent. Got 2 Photon SR and 2 Illumiknight as drops within 15 duels, and with the free copies from the mission, I have 3 copies each now.
I don’t have $hit. I got the UR and the SR cards you get my default for beating Kite. And after dueling him at least 30 times, I’ve only gotten one UR drop from him. Garbaj drops rate by far.
