Power of the Tributed When you sucessfully Tributed Summon "The Winged of Ra", its ATK will becomes the sum of the ATK of the Tirbuted Monsters, and its DEF will becomes the sum of the Tributed Monsters.
This deck is almost same as the basic Elements Unite deck to farm regular Legendary Duelists (LDs). If you are not familiar with it, check the link below. The one thing you must note is bringing Trap Jammer to negate the activation of Mokuba'sNegate Attack. This deck can't be used against Mokuba Lvl 30 since he has Poison of the Old Man.
Can be used to replace trap jammer, but remember to activate it during the start of the battle phase during your final turn.
Unhappy Girl (6k-8k)
If you don't have Paradox Brothers, use this deck. 100% win is not guaranteed, but works pretty well. If you are not familiar with this type of deck, check the link below to learn the basics. This deck can be used against Mokuba Lvl 30 as well.
Quick heads up, with the Rampage of the Forest box out, a Hey Trunade will force him to pick up his backrow before the final attack (besides the Gift of the Mystical Elf) Makes it just as easy as any other LD :P
He uses the Paradox's skills to have the big ass Guardian with 3750 atk.
I really don't get the reason to use these tricky deck... Just run the standard dark paladin deck to farm everyone else, with AMA. The second he summons blue eyes dark paladin goes to 3400, so he can't get over you. Last turn mokuba has 3-4 dragons is the grave so you don't even need to use darkflare knight.
