This is a two part topic. First off, can anyone tell me what walls of each type Wall Transform will apply? I'm pretty sure that Neutral = Wonder Wall, Green = Wall of Stone, Blue = Wall of Ice, but what about red and yellow? I believe red = Creeping Flame (Red's only defensive creature?) and Yellow = Tornado, but I'm not positive.
The next part of the topic deals with strategy for using this card. I'm sure we have all been the victim of an opponent transforming our prized land into a relatively lame wall, but has anyone tried using Wall Transform on themselves for their own benefit? I was thinking about running Wall Transforms in a variant of a powder eater deck. The idea behind this is to spread the puffballs around the map without necessarily boosting them and then transform them into walls in territories that will play a key role in chaining. One obvious downside is that Wall Transform costs 80G while I'm pretty sure all of the walls cost around half that. On the other hand you would save room in your book because you wouldn't need as many creatures, you can place a defensive creature anywhere on the board (assuming you have a powder eater there) and on any turn (assuming you have a Wall Transform in hand), plus you could always use the Wall Transform in the more traditional sense if your opponent has a particularly nasty creature holding land.
Anyone ever tried this? What do you think?
