First things first, most of my experience comes form the Career Mode but I’ve read Jason Klaczynski’s blog and played the Game Boy game. I’ll share what I like of the Base Set formats and the Rocket-on format.
Base-Fossil
If you never played this format and only go with what the people say, you may think that this format is just Haymaker mirrors. In reality this format has more depth thanks to the Jungle and Fossil expansions. I will not go in depth because you can just read Jason’s blog to inform yourself in the meta, and I just never played that many games outside of Career Mode, but I’ve played the GB game and finished it . In my opinion this is the best of all Base formats, because things get downhill from here…
Base-Rocket
This format is “What if we made Base-Fossil better but worse at the same time?”. And the awnser is make more broken Trainer cards and Dark Pokémon (Not dark type, that’s later). This format is really good unless you have a terrible case of bad luck.
Base-Gym
If you are into suffering, this is the format for you! You better have a ton of Basic Pokémon or really good luck because Trainer cards can become your worst enemy thanks to The Combo™ (If you don’t get it, you don’t get it.) But if you survive, then, you will find the greatest treasure of all PTCG… FUN! (But maybe not for you…)
Base-Neo
Remember this: “Cleffa is our hero. Cleffa is our savior. Always run 4 Cleffa. If you are not, then get more Cleffa.” Thanks to Cleffa the game got healthier, no more Combo™. But not everything got better, The Baby Rule adds more coin flips to a already coin flippy game and the format’s best attacker is also a coin flipper. And who is the best attacker in the format? Sneasel! A dark Pokémon (Not Dark, there is a difference.) who can deal a lot of damage thanks to Darkness Energy. There is also metal Pokémon and Energy (Not Steel, this is not the videogames.) While I think this format is better than the ones before, the flavor of Base set is kinda lost now. If you don’t like that flavor and don’t mind the coin flips, this is the format for you! (If you are playing slowking with the errata. If not, then… Why?)
Rocket-on
“What’s this? This is not a Base format!” That’s the “and More” part of the title. If you still don’t like any Base formats then you can try this one (It’s my favorite btw.) No more Energy Removals or Lass… (btw. Who is she?) It’s a less problematic format with a heavier focus in evolutions (And it has Ampharos.) It tastes like minerals! This is the peak of this era of the TCG because in the next set, the game changed forever… (Are you playing Slowking?! You are hopeless…)
About other formats like Prop 15/3… I’ve never played them and I have no opinions. Next up is e-Cards, the format that everyone forgot because it is in the shadow of it’s big brother the EX Series. In the meantime, why don’t you write down your favorite Base format and why?
P.S. I took me a lot of time to write this, It’s midnight now lol. Hope the next one dosen’t take me that long…
