Athena OTK

The Athena OTK is achieved by the effect of Honest and Athena, while you have Ultimate Offering on your side of the field. While you will take 500 points of damage each time, your opponent will take 600 points, so by doing it 14 times, your opponent will have lost 8400 points of damage, while you have lost only 7000. It is advisable to do this OTK only when both players' life points are at 8000, or when your life points are decently higher than your opponents (for example, your opponent has 3400, and you have 4000). Some of the cards that might be useful are Mysterious Puppeteer, which take out the damage from Ultimate Offering, and A Cat of Ill Omen, which help brings Ultimate Offering closer to your side of the field. Something that will really help is Hecatrice and Valhalla, Hall of the Fallen.
