Sweet (callous chuckle). I thought that it all appeared to be legal and made sense.
I've read a few comments about making the Wizard's Tower more expensive to cast, a higher level etc. Although I agree that it is powerful and, indeed, brutal, I don't think that it is as super as some complainers make it out to be. Yes it is an amazing attack to have and is worth every point of mana spent on it. However, in my last game, my opponents [mwcard=MWSTX2FFC03]Bloodcrag Minotaur[/mwcard] took it out with one attack (4 + 2 charge attack dice). Lucky dice roll with an exceptional amount of critical damage, you could say. Nonetheless, this shows that the tower is not indestructible and I think that to change anything with it now, or in the future, would attract more negative than positive reactions. I'm not sure whether Arcane Wonders would make such a big modification to a card, the errata on cards have been very minimal thus far and were for reasons in the interest of the health of the game.
Thanks for the replies guys.
