Card Tips:Terraforming

Instead of having 3 of the same field spells in your deck you can have two and use this to replace one of them. This is a good idea as you will have the same chance of drawing one of the 3 cards but you will get through your deck quicker and will be less likely to waste a draw on a field spell if you already have the one (unless you draw both your field spells before drawing Terraforming).
