In Soulkeep what it more important than towers and spells is their position in the map and this is pretty cool as a tower that have to be put near the gate you have to put it in this position and putting it in the middle of the map would not help and also at the entering of the soulkeep.
So you have to choose the right tower first and then you have to discover whether to use it near the gate or near the opening of fiends and also there are some towers that have to be put close to the corners that are between two ways and in this case you have to choose a tower with high range.
According to towers stats then you have to choose where to put it as a tower with high range could be put between two ways where fiends came in these area and also a tower with high speed could be put in a way where bloodlings came from and other that is so strong you can add it in a way of epic fiends.
This is the importance of checking every card stats and and to see how this card could do and does it attack flying targets or does it good with armors and so on the importance of a tower lie in where it could be put in the map.
