For new players to CCGs the sheer amount of 'pieces' in the game can be quite daunting, especially when you need to choose at least 50 scrolls to play the game. It's lucky that the symbiotic nature of the scrolls themselves (how they interact with each other), and that you aren't given all the scrolls at the start, will make it easier to learn the game as a whole.
By now, you may have chosen a resource type that your prefer, and this may be due to the 'flavour' of that type (eg the types of creatures or spells it has, or the characteristics of that resource). This alone is a great place to start when trying to learn the game. Whilst there are crossovers between resource types, in that there are similar abilities and traits, each resource type will have a theme and unique abilities which characterise it.
To learn how to play a CCG, you need to understand that everything starts with a single scroll; each scroll should be looked at individually. Pick a creature scroll at random from your preconfigured deck and do the following:
Look at its countdown, how often does it attack?
look at its attack, how much damage does it do?
look at its health, how much damage can it take?
does it have any traits or abilities? If so, when do these occur and what effect do they have?
does it have a subtype?
We now have the basis for your understanding of creature scrolls, every other creature scroll should then be compared to this scroll. In time, you’ll learn whether a scrolls characteristics are higher or lower than the average.
It may be that the scroll you have chosen is purely a mechanic scroll, in that its purpose is to perform a specific game mechanic such as draw an additional scroll or to attack/defend the idols. If the scroll effects other scrolls then take a look at those (if you don’t have them in your library then check the Scrolls Guide wiki) and see how they interact:
what makes them interact? Is it their type, sub-type, or stat?
do they increase/decrease a characteristic of that creature?
when and how often does it affect it?
As with my example, you may find a 'family' of scrolls which work well together. Not only does this give you a goal to acquire them, but it also means that when an opponent plays one of them in a game you can be sure that they may well have the others in their deck too.
Now that you know that there are groups of scrolls that interact in some way with each other, you can see that the focus of a deck may well be to get one or all of these onto the board. Other questions to ask are:
Spawn for growth, death for Decay, Resource Management for Energy, Positioning for order
If we look at the decay resource, for example, we can see that not only does it have a fair number of effective scroll combination (such as poison and curse) but it also benefits from both player’s creature destruction. Harvester is a very popular staple scroll for decay, a scroll that will mostly likely be included in the majority of a resource’s deck, and the various methods that Decay uses to destroy units and structures all go towards Harvester’s devastating attack. It’s important to not rely too much upon a single scroll or effect, though, as an opponent may be able to counter that particular strategy or the random nature of a CCG makes the likelihood of the combination happening less likely.
As I advised at the end of the Mulligan guide, it’s important that you reduce chance in your play as much as possible. The way to win the game is pretty much clear, and the ideal deck should allow you to have greater options and methods to achieve the goal of destroying your opponents idols. The greater the synergy of your decks, which you will learn by simply playing the game as many times as you can, the greater chance you have for success
