Dungeon [TCG Duel Field] (Patreon)

TCG Duel Field. The dungeon looks just like a card game board, and in this space, someone is playing a TCG match. The challenger seems to be treated as a monster in the card game.

In other words, the challenger is forced to follow the game's progression at that time, so it's a dungeon where anything can happen.

But a passionate duelist has no choice but to take on the challenge, right?
