[Scripting Question] Events based on Dex entries/completion

Hello,
I'm not really good at scripting but I would like to add stuff based on the completion of the Pokedex.
More specifically I would like to add for example two trainers. If the Player caught a Magmortar the the Event should activate a battle with a Trainer that got Electivire.
If the Player never caught an Magmortar the Event should trigger a battle with another Trainer.
So I would like to have a condition based on the Pokedex completion/entries not on the pokemons in the Team. It should definitly not be important which pokemons are in the Team.
Another example is, when the player got dex-entries for charizard and Blastoise and the Player talks to the Professor, a wild bulbasaur should appear.
Actually i am completely new here. i dont even know if i am in the Right section. Sorry if i´m not.
I hope you could help me and thx for every answer. ;D

should be put in a conditional branch of the trainer event. If the player has caught one then the Electivire battle happens or else not.

Do the same thing I said above but use this:
and have the Bulbasaur Event appear only if the above is true.
