Titamon

Let's hope BT24 give him support(since it TS theme) to make this deck better

For titamon effect you can use it to play Ginkakumom Promote for aggresive, Ogremon(BT14) for memory gain,Goblimon(BT17) to delete opponent level 4 or lower digimon or otehr femon card for more setup, you can also use Shamamon for floodgate despite he is red he is also part of [demon] so you can use titamon effect to play him.

I recommeded trash card like Nidhiggmon for memory gain or Underworld call for drawing if you have one in hand.

Since there isn't level 5 [demon] yet i use Cerberusmon can help you return [Shaman] in which you can return Titamon or Anubismon while x antibody which have trash and draw effect then play level 3 digimon, i also add anubismon since it have revival, trash card from hand while also delete level 5 or lower opponent if not draw 1
