This is my build for the Athena burn deck, but it still needs some tests for consistency. it's a pretty much do the OTK and do it well, or completely fail.
monsters:
3 athena
1 splendid venus
3 shining angel
3 nova summoner
1 honest
2 hecatrice
2 tehtys
1 sangan
spells:
3 valhalla
2 inferno reckless summon
3 celestial transformation
1 hand destruction
2 gold sarcophagus
1 monster reborn
1 heavy storm
1 dark hole
1 mst
traps:
2 call of the haunted
3 ultimate offering
1 solemn judgment
1 solemn warning
2 seven tools
Everyone usually focuses on the main OTK of special summoning 3 athena with inferno, then special summoning spam for 9600 dmg. I think this is a bit inconsistent because a lot of times you'll get too many transformations or infernos. Inferno is very circumstantial as well, so a lot of times you may not get to use it, or your opponent's monster may keep you from wanting to use it. I thought the idea of using honest's effect with ultimate offering was a way better idea because it is much easier to pull off and a lot safer. I'm debating on if I should take out a sarc or transformation for an extra mst because for the otk to work you really need honest. but of course if he does get destroyed, you can always bring him back with athena's eff.
