BT13 Mastemon

- I play three MagnaAngemon, even though many lists have moved to 0-1 copies. It gives the deck something else to hard-play T1, and I find that the Flame Hellscythe / Magna loop is backbreaking against various strategies that are looking for chip damage (which is why I'm on 4x Hellscythe as well).

- The lvl 4 package of Devimon / Angemon is cute, but I don't like weakening my security and the rookies in this deck can be key roleplayers.

- Speaking of rookies, I'm not leaving home without 4x Psychemon

- Speaking of rookies, I'm not leaving home without 4x Psychemon in the RK meta. Gazimon is flexible and a lot of decks that care about it can remove it trivially, but it can still be a nuisance and this deck really doesn't need the draw of Tapirmon.

- I've been trying the Ordinemon package, but there are a handful of downsides; people are very good at playing around it, the opportunity cost is high in deckbuilding, and you get enough recovery from Magna looping that it never felt like a gamewinning play. I've gone back to 2x DeathX, which will be especially helpful if Jumbo Chess becomes an actual roleplayer in the meta.

- Speaking of removing Ordinemon, T.K. gets a lot riskier with the higher purple count. If you're scared of accidentally having nothing to pick up in security, Kari can be a fine replacement, but I find the benefits of pulling yellow LV5s out of security outweighs the risks.

- Kazemon is a sleeper for most important card in the deck; it doesn't come up every game, but you'd be surprised how often your opponent plays around exactly the number of Digimon you have in play and then loses to "hybrid for game."
