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...
so i never really paid attention to it before but as of now i'm trying to farm the SDs too for keys and coins and at this lvl the star seraph deck is easiest to farm with cerberus so i always anticipate the SDs with that deck, however right now with all SDs there not a single one is using that deck?? i always thought every SD sticks to one deck but apparently it's random who uses which deck?? or is it not? honestly never bothered with that so i'm kinda confused right now?
cards i can think of right now to help you are eatgaboon for time wizard, also abyssal designator (take care of your life points tho) to get rid off any other monster, also try angel 07 (has the effect that other monster effects cannot be activated), and definitely de-spell/twister for that double coin toss spell card, if you have any high level monsters and no angel 07 out yet bring overwhelm too
OR: bring a waterdeck. theres this card, sea lord's amulett, that protects all water monsters from being destroyed by card effects for 3 turns. 3 cards = 9 turns in which your monsters cant be destroyed, unless of course the attacking monsters atk is too high. but in that case you still got umi to give you a power boost, and with a water deck its also super easy to get 5+ lvl monsters out quickly
Here is the auto duel deck I been using still testing in this bracket but it was 95% win in lower
I have no problem facing these duelist, its a challenge and its meant to be one at lv39. I do however disagree with Konami's choice of having NO HIGHER REWARDS, when beating these duelists. what a shame, might as well stayed at the lowest level possible if all the rewards are going to be the same... smh
