“The cards you have in your deck don’t matter” - that’s something that top players sometimes say. But what does it really mean? When it comes to answering that question, context is important. When you hear a top player say that, it’s usually when they just lost to a deck which they regard as worse than their own. And they might actually be right: they might have indeed just lost to an inferior deck. Their reaction, of course, is borne from the heat of the moment. But there’s something more to unpack here. Consider the notion that the cards you have in your deck do not matter, but that it is instead solely how you pilot your deck that determines the outcome of matches. Of course, on a basic level this is wrong – cards do matter. But the reason why it feels that they sometimes do not is that you’re probably testing your decks in the wrong way. This article will focus on deckbuilding – specifically, it will focus on how you can make sure that your deck is good after you’ve built it. Playtesting is not just important, it is essential – it’s how most top players prepare for big tournaments. Yet even top players – the same ones who may get heated in the face of an unhappy defeat – are usually doing it wrong when it comes to this key part of preparation. In this article, I will try and explain why.
