What is this?
This is a tool for comparing mana curves. It takes the mana curve of two players and simulates their card draws 1000 times to estimate which deck composition is better. If the deck contains less than 30 cards, zero cost cards will be added. If it contains more, the most expensive cards will be dropped.
How does the simulation work?
A deck of generic cards with the specified mana costs is shuffled. Player 1 is dealt 3 cards and player 2 is dealt 4 to start the game. Each player tries to play cards in their hand from most expensive to least expensive. If there is mana left at the end of the turn they will also use their hero power. If they have more than 10 cards in hand at the end of a turn, the lowest cost card is discarded. Once they run out of cards in their deck, they start taking Fatigue damage.
What is "power"?
This is a rough estimate of how much benefit a player gets from playing cards based on their mana cost. Some cards cost zero mana, but still clearly have some benefit, so we add one to the mana cost of all cards to determine their power. Hero powers are worth one power since they seem roughly equivalent to normal cards with zero cost (the actual mana cost is higher because they are always available and do not use up a card in the deck). Finally, each point of fatigue damage is counted as -1 power.
What do the graphs show?
The first two graphs show Power (in blue) and Average Power (in purple) as well as a vertical line (gray) to mark the first turn the player empties their hand on average. The third graph shows how the power balance changes as the game plays out. Each turn, Player 1's power is added and Player 2's power is subtracted. The more positive the graph is at any given turn, the more likely Player 1 would have won at that point. Similarly, the more negative the graph at any point, the more likely Player 2 would have won. Because the players don't play at the same time, Player 1's power is added each half turn and Player 2's power is added each full turn (which results in the zig-zag pattern).
