Normally, I have no problem kicking the crap out of Star Seraph. But this RNG.
Every single time I've played lately, she starts out with two equip cards and the Seraph, meaning every single game, she's got a 2400 atk monster with 2 500 atk counterparts turn one. Not only that, my hand has always been fucked as well- no equip cards, no way to get out Red Eyes.
Just my 2 cents for a good autoduel Mai deck. Better than 90% win rate and averages above 3000 rating. You can swap out Cyber for any 6 star really. Any 2 equip spells, and possibly skelangel to replace Senju and Sonic Bird if needed.
I've been using this deck for about 2 days now, with very high win rate (probably 95%+) against all lv39 SD even with those annoying dino and time wizard decks. The sole purpose for this deck is to farm 10-sided dice (Yami Bakura event) so dont expect high score assessment (2500 avg, max about 4000). Sadly, this deck is only for Yami Yugi (and by the time i write this comment my Yami Yugi already reached lv 33).
Could you guys pimp my deck against the overall LV. 39 SD? I guess my machine monsters has a good sinergy with and velocity, with high atack at low cost. Altough this deck has been giving me a good win rate, I guess it could do better...
