Prize cards are a horrible mechanic, sometimes locking key components of your deck (needed to get the engine going) behind knockouts.
True, but unfortunately it has been that way since the TCG began. I used to praise the Prize mechanic because I approached the game from a "This gives me a chance against good players!" instead of "Wait, this is another way the more skilled player can lose just due to bad luck." Like most applications of "luck" in this game, there is a certain element of skill added by the Prize mechanic as well. Yes, I read the other comments in this thread.
Would I love to see the Prize mechanic revised or even totally replaced? Yes.
Do I think it will happen anytime soon? No.
Does anyone on the Dev Team have anything to do with revising the TCG? No.
I suppose we could ask them to create some sort of "Manual" mode where the games no longer carries out your selected plays automatically, but instead you have to use dropdown menus and/or keyboard shortcuts to tell the game what to do... and in doing so, you could try homebrew rules with your virtual collection. I'd actually enjoy that quite a bit. I may have to suggest it in a separate thread.
Other than that, the Dev Team cannot "fix" the Prize Card mechanic anymore than they can fix the x2 Weakness mechanic, the VG-to-TCG Type conversions, the massive amount of "filler" cards, raising HP scores while keeping damage output, properly balancing out the Evolution mechanic by slowing down the offensive capabilities of Basic Pokémon while simultaneously making Evolving Pokémon more useful in setting up, etc.
