If you could choose the next previous Starter Pokémon for a 7-star Tera Raid, what would it be and why?

I would like to see Serperior and Emboar!! I know it's unlikely but I just want the other Unova starters to be available in a switch game :(
Samurott is my favorite but I ADORE all 3 of the Unova starters (and for that matter, the whole Dex) dearly, and I wanna be able to use them.

To be fair, I see no reason that every Starter shouldn't be included in the game anyway.

even though he isn't in the game yet, I would like incineroar. He was my first pokemon ever and would be a blast to use competitively.

I want my big stupid happy Meganium boy back!

 

[Sweet Serenity]

I would love for Feraligatr to come back. That would be awesome.

Meganium. Love this starter and I want them to make it pack a punch in some way too, even if I'm not counting on it. Give me my grass baby!

Even though I wouldn't likely use it for anything, my very first favorite Pokemon was Blastoise, so it would be cool to see that one as a Tera Raid. Charizard gets so much love, where's the love for the other OG starters? >:3
