managed to finish almost all mission except floor 50. I have never opened any Stardust Acceleration pack. any suggestion of a good deck i can use with Mark of the Dragon - Head against the final boss for that one mission? or I just have to waste gems for a card I rarely use?
I found it really easy to do by using Mark of the Dragon - Head (I don't own Stardust eiter), and focusing on a double syncro summon. I try to get Armades out and beat the Creator down to no LP before summoning Stardust, since he has quite a few annoying traps. Lightning Warrior is there if you have no choice and need a strong monster out fast.
So long as you don't attack, the creator deck doesn't have anything that can get past Lightning Warrior, and a 1* tuner on lightning will turn him into Stardust. Stardust can use his ability to revive from Sakuretsu Armor, so only Mirror Wall is a danger. The AI is really obvious when it has Mirror Wall, as it'll move it's monsters to attack position.
