"Will anyone build the Crystal Vein/Fastbond/Crucible deck? Obviously this card is best used with Fastbond (which is restricted). Will it be used in any other deck than a Fastbond combo deck? Probably not, but you never know - a Goblin deck might want to recur Wastelands every turn of the game - or some deck might want to bring back a slain Mishra's Factory every turn. Zvi's Turboland deck has never been accurately translated to Type One, even though it has a bazillion more tools to work with in this format and has been a proven winner in several Extended metagames. Look Type One people - another deck for you to stea... errr, borrow and retool!"
First of all, however, the combo has it tough since you can get infinite mana off just two cards. For example, you have Grim Monolith / Power Artifact, Animate Dead / Worldgorger Dragon (and a land in play), Metalworker / Voltaic Construct, and most recently, Auriok Salvagers / Black Lotus (or Lion's Eye Diamond).
