pokemon base booster box 1st edition Set 320: 1999 Pokémon Base Set

In a rotisserie style of event with lots of sideboard slots available you might consider a learn card and a couple of lessons but even then I doubt it

Alternatively, you could forgo Meowth and the Red Card to instead bring along Growlithe and Arcanine ex if you have them

And Masters of Evil will, of course, have all the baddies you could hope for

It ended up being a lot more interesting than I expected

This deck features 20+ counterspell spells (instants), and in addition a number of your creatures add additional counter abilities, such as Voidmage Prodigy, which can turn each of your wizards into a counterspell

There were several Basic Pokmon-GX such as Rayquaza-GX, Lapras-GX, and of course more recent stars Buzzwole-GX and Blacephelon-GX
