This deck uses a part of the old Alphamon base and the Gankoomon X/Sistermon combo.
The best play is to evo a sunarizamon in raising up to a Dorugreymon or Hisyaryumon with a memory tamer or Yuji on the field. Up to this point if you have Sistermon you need to hard play and start attacking so you have her in trash. After you promote you can evo into Gankoomon x, play sistermon, get all the boosts. Then evo into Jesmon GX and put the old Gankoomon as source to delete the lowest play cost and swing. With a good stack you will have a Jesmon GX with +3 security and 21k that reboots into a 20k blocker with protection from bouncing and dp reduction.
I also play ryudamon and kongou as protection from deletion or chaos degradation. I do not use Kota as tamer as he bottom deck my pieces.
