it does not digivolve because it is a mega
To get shinegreymon burst mode you must DNA Digivolve shinegreymon with galletmon (Galletmon is one of the royal knites) or you could DNA Digivolve shinegreymon with another digimon i forgot (that info is if you dont have dawn) The conditions are lvl 66+dragon exp past or at 40,000 and holy at something
You must DNA Digiviolve shinegreymon and galletmon.But you cant get it unless you befriended shinegreymon RM to get him you must DNA Digivolve shinegreymon and darkdramon.There levels have to be past 66 and some other conditions i dont know........Sooooooo.....Yeah.....Good luck with that.
Marcus' partner is Agumon and he can digivolve to GeoGreymon and then to RizeGreymon and then to ShineGreymon, Thomas' Digimon partner is Gaomon and he could digivolve to his Champion level form of Gaogamon and then to his ultimate form of MachGaogamon and then to his mega formof MirageGaogamon, Yoshi's partner is Lalamon and she can digivolve to Sunflowmon and then to Lilamon and Rosemon and Keenan Crier's Digimon partner is Falcomon and he can digivolve to Peckmon who could digivolve to Crowmon and then to Ravemon.
The line goes in 3 directions, which is either: Botamon > Koromon > Agumon > Greymon > MetalGreymon > WarGreymon Botamon > Koromon > Agumon > Tyrannomon > MetalTyrannomon > BlackWarGreymon Botamon > Koromon > Agumon > GeoGreymon > RiseGreymon > Shinegreymon SkullGreymon is another alternative evolution from Greymon.
Even though I like Tai better than Marcus, I'm not going to be a fanboy and say Tai wins like most people do. When you think about it logically Tai's Agumon can only digivovle up to it's mega level, which is WarGreymon. Marcus' Agumon can digivolve into it's mega level, ShineGreymon, as well; but Marcus' Agumon doesn't stop at it's mega level. Marcus' digivice lets him activate his ShineGreymon's Burst Mode, which lets him increase ShineGreymon's strength by twice as much and achieve power greater than mega level and become ShineGreymon Burst Mode. So by achieving strength greater than mega level, ShineGreymon Burst Mode would beat Tai's WarGreymon.
huge
Probably SHINEGREYMON, but if you want to go further there is the Burst Mode and Ruin Mode of ShineGreymon.
Calumon does not digivolve, he actually makes other digimon digivolve, but he does not.

SaberLeomon can additionally digivolve into Dinotigermon.
Digivolve Megadramon or DNA Digivolve MameTyramon and MetalGreymon
It matters about the digimon, if you pass time it might digivolve to another digimon while some of them digivolve to another digimon if you have like 3 or more battles to make it digivolve. for an example: Greymon will digivolve to MetalGreymon with at least 10 battles, or he'll digivolve to MetalGreymon(Virus) if he has 30 Vaccine AP or he'll digivolve to SkullGreymon if you pass time. understand?
