Hunters
Note: due to how the deck is multicolored, the deck ratio can be altered depending on the match ups or what cards are deemed more important
Win Con: Beatdown. Most of the time, you will just be attacking with your lvl 3s or lvl 4s to crash into security. Also, set up as many tamers as possible to get the engine going. Hard play your lvl 3s and lvl 4s even without digixrosing sometimes to help you either set up or cycle through your deck. Your level 5s are what will most likely finish the game at the end.
Key Things:
Save: Almost All your digimon have save in their text. On deletion Save lets you place that deleted digimon and place it under any 1 of your tamers. The lvl 4s let you also place another digimon with save in its text from the trash to another of your tamers. (Note: Monimon on deletion draw won't activate if the card was saved first because of rulings, so draw first from Monimon egg then save)
DigiXros -X: When you would play a digimon with DigiXros requirements, you may place card under the digimon you are playing from either your hand, battle area and by tamer effects. For each material DigiXros Material placed underneath, reduce the play cost by -X.
Tamers (BT12 Taiki, BT12 Yuu, Tagiru): Both Taiki and Yuu lets you load Digimon under the, at the start of the main phase to either draw 1 or gain 1 memory respectively. When you would digivolve 1 of your Digimon, each tamer lets you tuck under 1 digimon from under any of your tamers and place it at the bottom of the digimon you're going to digivolve and reduce the digivolution cost by 1. You may tuck as many digimon cards by the tamer effect underneath the digivolving digimon even if the digivolution cost already is free.
Boss Monster: Arrestradramon: Superior Mode - Lets you place an opponents a lvl 3 Digimon to be placed underneath another digimon or tamer (considered as one of the most powerful removal). For each tamer you have with a different color, increase the lvl by 1 (which likely you will have at least 2-3 set up before going into this card). It's end of turn let's it attack without suspending (as long as you have 4 or more materials which is likely) meaning it can attack even while suspended, pretty much can attack twice in 1 turn.
Emergency Boss Monster: Quartzmon - the only lvl 7 but no lvl 6 in the deck. It's alternate digivolve cost lets you digivolve Quartzmon from one of your lvl 5s w/ save in its text but for 9 cost instead of 6 cost. Stuns/Suspends the entire board permanently until Quartzmon leaves the field.
