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.
Fast farming deck that doesn't require any character specific skills. Against level 40, you'll need to get Transmodify early since you can't stall the turns by simply using an 1800 attack monster. Odion has 3 attack increasing equip cards, which also means that you need to finish the duel early before he stacks all 3 on 1 monster to get over your Tethys. For a more safer farm attempts, you can duel against lvl 30 instead.
Elements Unite! (8,000 +)
Odion's highest defense monster is a Giant Axe Mummy with 2000 Def. However, it can't do anything after you special summon your Gate Guardian. You can check more details and information regarding the deck by clicking the link below!
Summon the unhappy girl, or rai-mei if you don't have her, and pass the turns to stall the duel until you can perform the gravekeeper vassal and union attack combo. Once you summon the unhappy girl, set rai-mei again once you have enchanted javelin to raise your LP. This will make sure Odion won't attack, otherwise pumpking with castle of illusions to deal more than 5000 damage with 3 monsters.
It's funny. On my second account, it's Giant Axe Mummy that's the impossible one. Which is fine, given it's completely useless (if Great Moth and Serpent Night Dragon weren't SR, it would probably be the outright worst SR drop).
Merciless Trap Hell
Inflict 500 effect damage per chain by trap cards.
This deck pretty nails it for both Tea and Odion. Pretty affordable sans the Legion The Fiend Jesters and the Union Attacks (that I got from the Yugi Muto unlock event tho), makes 6,5k to 8k pretty constantly
Did he attacked with Mummy? If yes, it's because of mechanic change announced a few months ago where UG can be cancelled with flipping face down. Hence AI attacks since they know they can always flip out of it.
