Hi everyone,
This deck hero is based a hunter.
I use 4 koromon but if you want use a option red cards, gurimon is a better egg.
Superior mode bt12 is good but this card has no synergy with agunimon and lvl 6 hero. That's why there are 3 copies of it.
Tai is setter and gives +1 security to all your red cards (watchmaker). If you need draw another option is Tai black for the digimon's raid or Tai BT21. You can also remove Lui and add a red option card such as Crimson blaze or Fire Ball/Rowdy Rocket (draw 2).
You can use these staples:
Imperialdramon BT20
DeathXmon
Medival
Crimson blaze
Any change you think is a better option, you can let me know on Discord.
