Not my idea, but an interesting play I saw somewhere on youtube.
Made a few edits to suit my preference and just sharing it.
Literally just hard calling 6 Cost lv5s and trying to digivolve into dorugoramon.
With dorugoramon's on atk, putting another dorugoramon, OmnimonX and Alphamon into the source to be spawned out by the blue options.
The Veemons is just there to draw and to enable the use of the options.
Ultimate Connection is used when you have too many cyborgs and not any Xanti-bodies in hand.
Havent tried it out myself but it seems it is going to be fun to play.
