I'm wondering if the caster is free to choose any direction for the "Wall of Pikes" card. I realize that the flavor text says "always make sure the pointy end is facing the enemy", but is it actually illegal to set it up with the pikes facing the caster?*
Also, if you choose to extend the spell, does the facing have to be the same for both parts of the wall, or could you set up a 2-square linear wall with one section facing left and the other facing right?
*The tactic I'm thinking of here is using inward facing pikes to trap an opponent into a corner along with my forcemaster. The forcemaster can do solid damage with Galvitar up close. And not only does the opponent take damage if he runs away, but you can suck him right back in cheaply with your force pull! Best of all, if your opponent summons in lots of creatures to help him out in there, a simple 4-mana "Repulse" spell will damage every other creature in there with you, either by pushing them through the pikes, or smacking them into the walls. Unlike all the other force-pushing spells, "Repulse" doesn't seem to have any restrictions about pushing through passage-attacks walls.
