NOTE: Although the original intent of this article was meant to help Cardfight!! Vanguard players when it was written, the concepts described in this article can be applied to any card game.
As a term, card advantage describes the state in which a player generally has more cards than his or her opponent. With this in mind, the theory around this concept describes how the player can achieve card advantage and how to measure it.* Although the theory is not perfect, the basis of the theory is that the player with card advantage has access to more cards than the opponent, meaning that the player is closer to drawing his/her deck’s win conditions than the opponent. This is especially important for slower control decks, which focus on gaining card advantage slowly before finishing off their opponents.**
In the game of Cardfight!! Vanguard, the total card advantage that a player has not only refers to cards in hand, but also the cards that are on the rearguard circles. Conserving card advantage in this game could make the difference between having enough cards at the player’s disposal to guarantee a winning game state, or the exact opposite. Although this is concept is being applied to Vanguard in this article, this concept can be applied to almost any trading card game in general terms.
NOTE: This article is mainly used as a guide to measure tangible card advantage in the game of Cardfight!! Vanguard. This method is not easily applied to virtual card advantage, which is described at this link.
Measuring Card Advantage
In Magic, players tend to measure gains or losses in card advantage in a way describes trades in resources. For example, if one card’s effect allows the player to force the opponent to discard two cards and the player to discard the card after the use of an effect, the player traded that card for two of the opponent’s cards. This, in Magic: The Gathering, is known as a “two-for-one”, describing the transaction that took place.
The approach this article will show the player is also taken generically without specific vocabulary, which allows the player to easily gauge the amount of card advantage being gained or lost in the course of the game. Specifically, this approach tracks the net card advantage between the two players in the game of Cardfight!! Vanguard.***
When describing net gains and losses of card advantage on the board or out of hand, there are three ways to describe such trades:
- Negative cards. Also described as a “-(number of cards lost)”, a net loss happens when a player loses one or more cards of advantage compared to the opponent’s cards. An example of this is when a player loses a rearguard due to an attack. This rearguard is discarded without the opponent losing any cards from field or hand, meaning that the player has lost one card in advantage.
- Positive cards. Also described as a “+(number of cards lost)”, a net gain happens when a player gains one or more cards of advantage compared to the opponent’s cards. An example of this is when a player draws a card due to a unit’s on-hit ability to draw a card when it hits an opposing vanguard. In this instance, a player that is able to draw a card without having to discard cards from hand or lose rearguards, which equates to +1 net gain (assuming the opponent does not gain cards due to the skill).
- Zero cards. Also described as a “0”, netting zero happens when a player gains no more cards of advantage compared to the opponent’s cards, even in spite of a trade or transaction. An example of this is when the player activates the ability to drop one card and draw one card. The player loses one card (-1) due to the drop part of the ability, but gains one card (+1) when he or she draws one card. The net of this transaction is 0 (or 1-1 = 0).
Applications of Measuring Card Advantage in Vanguard
This style of measuring card advantage can be tedious during game play, especially for those who do not wish to keep track of facts and figures while keeping trade of card skills. With this in mind, here are a few ways to apply the theory discussed here.
- Analyzing card abilities. This method of analyzing card advantage can be used in the process of deck building to decrease the amount of inefficient cards due to the cost of abilities. In addition, this method can also be used to compare similar cards by comparing their effects on general card advantage.
- Making better trades in battle. In the midst of game play, choices like attacking the vanguard versus attacking the rearguards can be crucial in taking advantage away from the opponent or obtaining advantage for the player. For example, if attacking the vanguard will force the opponent to guard with two cards compared to guarding the same attack directed at his/her rearguard with one card, then attacking the vanguard is a better choice in terms of card advantage (aka forcing the opponent to -2 instead of -1).
