Yes, but the point is: before our game you'd have to tell me, because I keep forgetting what those two are (I know one of them is Izamu, but wouldn't even know which one). Same with some of the alternate sculpts. You'd have to tell me.
And that is where the argument breaks down. If you can tell me what those are, and I remember throughout our game, you can tell me about your Pikachu, too.
Let's face it, there are tons of games where conversions and (sensible) proxies are allowed even in tournament games, and guess what? The world hasn't ended. It's just not such a big problem. And even though I'm sure evevry so often somebody would turn up with a lame Pikachu, there'd be countless awesome converted and proxied miniatures (maybe even a cool looking Pikachu) that would enrich the game.
This isn't about the money, you know?
