Had a lot of fun with the alliance/Mother D combo so here's the version I came up with.
Alliance with your Mother D to swing for two checks at a minimum of 19k dp, then the level 3 inherited to digivolve mid attack for -2 cost. Then you suspend your Davis & Ken to unsuspend your new 2 color lvl 5 alliance, activate the lvl 5 [end of attack] effect, and now you're unsuspended and can attack again if you want.
Your lvl 3s will let you search for 2 color green cards so you can pull your Davis & Ken that way or really any card you need.
Update - multiple new combos
Leaning into purple a little harder now to play or recycle from trash.
Trying out using wormmon DNA into Ordine at end of turn. You can hard play a level 6 next to your first stack to end your turn and then they go into Ordine.
This was a lot of fun but it's still a work in progress so any suggestions would be appreciated!
