RtR had Chromatic Lantern at rare and Transguild Promenade at common to assist with generic mana-fixing on top of gates/keyrunes/shocks. In GTC we now have Thespian's Stage as a rare fixing/utility land, so it seems like we might see some sort of common or uncommon artifact to help smooth mana in limited. Of course it's possible that the two sets won't mirror each other and we've seen all the fixing we're going to get.
How about "You may discard your hand, pay 5 life, rip this card, remove 3 digits from any number of target fingers you control, and concede at the end of the next end step rather than pay It Will Go Through!!'s mana cost.
Thoughts/ideas?
