I might actually be in the minority here, but I think Counter Catcher could be pretty busted, I know you have to be behind on prizes but I think it could be a very frustrating and spammable card when you are.
If you are in the minority, it is because more recent players need to study (as best they can) the history of the game. We've had a card like this before:
Pow! Hand Extension. It was a pretty potent card. Obviously, things are different now and then, but the many factors make it hard to predict if
Counter Catcher will be better or worse, at least relative to the format in which it finds itself. The Prize count is a dubious means of measuring who is winning until someone has taken all of his or her Prizes.
It's a bit funny how people always proclaim Brigette would be "broken" because you can search 3 gxes from your deck, although the card is actually much stronger and more important in Gardevoir/Metagross, decks that use it exactly like it's intended to be used...
It is not funny how people forget or remain ignorant of the game's past.
You mention how the card is stronger and more important to some of the current Stage 2 decks; this is true
for now. When
Brigette released, the abnormally strong Basic Pokémon - Pokémon-EX - were speficially singled out as gaining a lesser search effect. This is because the game's designers remembered how often big, Basic Pokémon could dominate the metagame; it has happened numerous times throughout the game's lifespan. Recently released cards single out Pokémon-GX and Pokémon-EX when an effect works only against them or for anything
but them.
Put it all together and
Brigette is in a high risk situation; we are just waiting for there to be the right combination of big, Basic Pokémon-GX that work well together as a deck
without having a coming-into-play effect, and
Brigette will clearly favor such a deck. Please also note that the decks you cite, while competitive, are also still fairly recent. If the powers-that-be were to revert to the original "first turn rules", as they have once before, pretty sure most Evolution heavy decks would take a serious hit.
Why would Bridgette be "broken" when it's the classic staple of "Search 3 basic cards" like Pokemon Collector, Call for Family, Hit and Run...? It's the newest version of those historic cards and to be fair what makes evolution decks playable. The game always had cards like these.
Apples to apples; attacks like "Call For Family" or "Strike and Run" are or were just that: attacks. The big concern is how you can field multiple Basic Pokémon-GX in a single turn and still have your attack available. I'm glad you brought up
Pokémon Collector; it was more than a little broken when ZPS and later ZPST decks began abusing it. In the Legacy Format, we've seen what
Pokémon Collector can do with Pokémon-EX, as well.
To
both of you, what makes Evolutions "playable" in the Pokémon TCG is
breaking them (or at least close to it). I believe the game could more or less balance out the different fully Evolved Stages of Evolutions
but after almost 20 years, they rarely take the actions necessary. You need to be able to spam multiple copies of your Basic Pokémon
because there are enough other Basic Pokémon capable of rapidly OHKOing your own; if you don't drop multiple copies of key cards, good chance it won't survive to Evolve.
