You draw cards, then burn and win, the deck's weaknesses are many, bricking, drawing sharkpedo too early, being caught by handtraps,...
Heresy About Torpedo FTK

Torpedo Takedown and Humhumming the Key Djinn (boom)
Torpedo Takedown
Target 1 WATER Xyz Monster you control; detach 1 material from it, inflict 400 damage to your opponent for each card in your hand, and if you do, that monster gains ATK equal to the damage inflicted, until the end of this turn. You can banish this card and 1 WATER Xyz Monster from your GY; draw 2 cards. You can only use 1 "Torpedo Takedown" effect per turn, and only once that turn.

Jump yourself by showing a Level 7 or higher monster (so you can easily get Tethys), it also has a 2nd effect... well, no one cares in this deck

Insert it to draw or Angel O1 jumps, don't insert spells/traps because doing so will cause Tethys' draw to be interrupted continuously, which is very annoying.
