Dynasmon too me is still best with Sylphimon (like in the original Win% card), but I understand people not wanting it with a Digimon who already had a pretty well established final form in Valkyrimon. Even with that, I think humanoid Digimon with Wind powers like Karatenmon and Shutumon work fairly well if it. I would even advocate for Gigadramon->Dynasmon since I like to keep all that purple and MasterTyranomon/Cyberdramon because they go well with most dragons. I hate Mistymon with it but, yes, it is the line that people like more.
Duftmon, I think people most often use the usual Liollmon->Leomon->GrappLeomon->Duftmon, not that I think it is best but it certainly works as a lion inspired line. Personally I think Mihiramon, Nefertimon, TobuCatmon and the true dark spirits also deserve a mention.
For Gankoomon, the general line is Cyberdramon->Gankoomon with a variety of dragons behind but I think MasterTyranomon, SuperStarmon and especially DeathMeramon deserve a mention.
Craniummon, the SkullKnightmon line, the Andromon line and Drimogemon->Giromon are normally somewhat connected to it but I wouldn't rule out other options like Cyberdramon (2010), Piccolomon, DeathMeramon and even corrupt Grademon.
