Promote Palmon (BT22-044) under a champion. Use the [main] inherited effect to tuck, gain a memory. If you get yourself to 4 memory (say by using Kuremi Detective Agency (BT22-099)), you can go into Hudiemon (BT23-101). Use her [when digivolving] to play out Chitose Imai (BT23-081), then use his [on play] to play out a champion. Attack with Hudiemon, then use the [when attacking] to bounce Chitose to hand, and then play him again with the [on play] trigger, as well as getting another trigger on Chitose's [on play]. Suspend for alliance, make two checks.
Next, DNA digivolve your Hudie and another champion into Shakkoumon (BT23-032). Because he's a CS trait digimon, and technically a new digimon, we can use Palmon's inherited effect to put Shakk on the bottom of the stakk, conveniently leaving Hudiemon on top. Repeat the process with Chitose and champions to make two more checks, then DNA digivolve her again into either BT23-032 or one of your other DNA ultimates for the last two checks.
