Deck Building Basics: Why Your First Deck Loses
Consistency, curve and cutting your favourite card. The principles that apply across every trading card game, physical or digital.
The short answer
First decks usually lose because they contain too many different cards, which makes drawing the pieces you need unlikely. Running multiple copies of fewer cards, respecting a resource curve, and cutting cards that are individually strong but do not fit the plan produce far more wins than adding powerful singles. Consistency beats power in almost every card game.

My first deck in every card game I have played contained sixty different cards, every one of which I thought was cool. It lost to decks with a fraction of the interesting cards, over and over.
The reason is arithmetic, not luck.
Consistency beats power
A deck that does the same reasonable thing every game beats a deck that occasionally does something spectacular. Drawing your good card once in five games is worse than drawing an adequate card every game.
The three problems with a first deck
Run the minimum number of cards
Every card above the format minimum reduces the chance of drawing your best cards. This is not a preference; it is the maths of drawing from a smaller pool.
Players run over-sized decks because cutting is uncomfortable. It always is. Do it anyway.
Run multiple copies
If a card is central to your plan, run the maximum copies allowed. If it is not worth multiple copies, ask whether it is worth one.
There are exceptions: cards you only want to see once, cards with a restriction, situational answers. But the default should be multiples, and beginners default to singles.
Have a plan and cut what does not serve it
Before adding a card, answer: how does this help me win?
"It is a strong card" is not an answer. Strong cards that pull in a different direction make a deck worse. A deck that attacks quickly does not want expensive defensive cards, however good they are in isolation.
This is where the favourite card gets cut, and it is the most reliable single improvement a beginner can make.
The curve
Your resource curve is the distribution of costs. A reasonable starting shape for most games:
- Majority cheap — things to do in the early turns
- A solid mid-cost core — where most games are decided
- A small number of expensive cards — finishers, three or four at most
- Enough resources — the ratio your format expects; under-running resources is the most common structural error
The failure modes are symmetrical: too expensive and you lose before you function, too cheap and you run out of impact.
Testing
Play the deck ten times before changing anything. Note which cards you were pleased to draw and which you were not.
The cards in the second group are your cuts. This is more reliable than theorising, and ten games is enough to see the pattern.

Key takeaways
Frequently asked questions
Why should I run multiple copies of a card?
Because a deck is a probability exercise, and a single copy of a card in a sixty card deck is drawn rarely. Running the maximum allowed copies of the cards central to your plan is what makes the deck do the same thing reliably. A deck of singles does something different every game, and mostly something worse.
How many cards should my deck have?
The minimum the format allows, in almost every case. Every card above the minimum dilutes your best cards and reduces the chance of drawing them. Players add cards because cutting is unpleasant, not because larger decks perform better. They perform worse, measurably and consistently.
What is a curve and why does it matter?
It is the distribution of resource costs across your deck. A deck full of expensive cards does nothing in the early turns and loses before it functions. A deck full of cheap cards runs out of impact later. Most decks want a majority of cheap and mid-cost cards with a small number of expensive finishers.
Should I buy the best cards in the format?
Not initially. Expensive staples improve a deck that already works and do very little for one with structural problems. Learning to build consistently with inexpensive cards makes you better at the game and makes any later purchase more effective. Most beginners buy power before they need it.
