I don't know if this has been posted but I find this core to really cover a huge majority of the metagame. The only pokemon you are outright losing to is a +1 volcarona. Other than that I can't think of a standard pokemon that can break this core easily. With some hazards up (2-3 layers of spikes) this core becomes way more powerful and easier to play with. Jirachi covers the hurricane spammers and most lati@s sets. Land-t covers most physical sets with ease. Garchomp and terrakion would love to go one on one with rotom and jirachi but it has a difficult time KOing land-t. Land -t also has the speed to be quite a late game threat with jirachi or rotom's paralysis. Rotom covers some awkward threats that would kill jirachi and land-t like mamoswine and rain teams. Pokemon like ferrothorn can give this core some trouble due to its unpredictability but you can throw on superpower or fire punch on land-t and jirachi respectively . Also you have to watch out for scald as a burned rotom isnt really productive. Scald in general is just a scary move.
