What combination of moves, abilities, and type would have theoretically the best super-effective coverage?

Question

the moves include all moves from the Pokemon database, combination should be able to hit most Pokemon for supereffective damage. and if such a Pokemon exists, what would be the best counter to this Pokemon?

Comments

I changed the title to focus on type coverage as opposed to the "strongest Pokemon" (which could mean anything so isn't appropriate for this platform).
These questions are similar to this one and will likely lead to an answer:

This answer in particular takes all of moves, abilities, and type into consideration while figuring out the best super-effective coverage out of 4 moves. Would this count as a dupe?

They are different questions, so no.

Do you want to ignore the target Pokemon's abilities?

i guess we should consider the targets abilities too

Can the user have flying press, freeze-dry, thousand arrows, mold breaker, or scrappy?
