My apologies but as it turns out Asuka has confirmed that my approximation of Treasure Chest's deck is "wrong". I don't know the extent to which it's off (Treasure Chest's current AI deck is something Asuka may take with him to his grave), but things I can confirm are that:
-Treasure Chest used 3 copies of Petrify against me in its first 13 cards. From what I have seen from AI characters with possessable decks, they do not discard cards and will use each card.
-Treasure Chest used 3 copies of Mountain Strike against me in its first 14 cards.
-Treasure Chest used 4 copies of 5 Attack (now 500 Attack) in its first 6 cards against a player on a video I'd seen (Quietube isn't working for me but the video is entitled "Treasure Chest Trap Compilation" by OniBladeMaster with the relevant encounter being from 4:22 to 5:23 of the video.) None of these attacks were Crush as the Treasure Chest didn't have shields up at any point during that particular fight. In my encounter with it, Treasure Chest's fourth 500 attack was its 19th card used together with Poison, so I'm fairly certain that however many cards Treasure Chest has, it's larger than a standard 15 card deck.
-Treasure Chest definitely uses 200, 500, Crush, Stone Strike, Stonewall, Poison, Petrify, and Mountain Strike, it's just a question of how many copies of each card it uses.
-The quantity I was most unsure of was Poison, but it did use 3 against me in 20 cards and 5 against me total by the time it had used 27 cards within a single encounter so I don't think it can be less than 3. Even if it had a 15 card deck, it wouldn't be able to use 5 Poisons before 30 cards without having at least 3 so I reasoned that it had 3.
My approximation of Treasure Chest's deck is likely close, but I can't be sure. Predicting an unknown deck from the cards it uses within a certain number of usages is not an exact science and there can be strange in-battle bugs or other complications such as cards not loading.
I will try to do more tests later on to better infer Treasure Chest's deck, though even if I were to find the correct list I wouldn't receive any confirmation from Asuka or he would've put it on the Wikia already. He is withholding the information and to be sure I'd have to either find it out from someone else with access to Treasure Chest's data or mathematically deduce it beyond a shadow of a doubt somehow, which is complicated by the fact that it probably has more than 15 cards in its decklist and probably fewer than 10 trillion but other than that it's hard to get a handle on just how many cards it could possibly have.
