The 2021 Tin of Ancient Battles builds (literally!). (Most Duelists never noticed, but the 2020 tins, and now the 2021 tins, have embossed/debossed sides, and rimless lids that fit flush with the tin body, allowing the tins to be stacked on top of each other to build the entire Pharaonic tablet – once all three pieces have been assembled!).
