For the era of warp evolution or spirit evolution to jump or skip the normal evolution line to reach LV6 or LV7 Digimon with just paying a few more memory during digivolving or attacking in BT6 and BT7 meta, "speed" or "cost" is becoming the first thing to consider when you build a deck to play a competitive game or participate tournaments. Is your deck fast enough, or if the opponent is faster than yours then how you are going to counter that? This is the reason why black decks like X-antibody or Machindramon still find it very hard to be in Tier-1 or Tier1.5 of this meta.
Let get back to this green gatcha profile, if we calculate the cost to have 1 or 2 security checks, it takes 6 costs for 3 attacks (best scenario), equal to Rookie Rush speed when we use 6 memories to play 3 rookies that contribute 3 security attacks. This deck almost never have to pay a cost when we would digivolve from a LV5 into LV6 Digimon, there are many solutions you can play around with to get the most wanted LV6 Digimon to be digivolving.
This featured deck comprises 11 LV3s, 9 LV4s, 10 LV5s, 11 LV6s, and 3 LV7s Digimon. There are 6 tamer cards and no option cards. The distribution is already showing the first weakness of this deck: hand-brick, lol, so to avoid this you must do a proper shuffling (for example table shuffle).
