2 ash is never correct, just play 3. It makes no sense to play only 2 of the best handtrap in the game. You should play 3 imperm and 3 veiler too. You need at least 12-18 cards in your deck to be handtraps and/or boardbreakers to survive in 2024 yugioh, even in Underdog format. Otherwise you’re going to get full comboed. Also crossout is being played, so you really need to draw 2-3 hand traps, because 1 of them is probably getting crossouted. You should slim down some of the engine pieces to fit more handtraps/boardbreakers.
