I just finished building my first Shards-Conflux Sealed Deck pool and I am really confounded as to the viability of a number of the commons. Ruptured Spire is the one giving me the most fits — as it seems to be doing for many of the players here.
It basically eats a whole turn to come online since you have to play it tapped and pay 1 when you do. I have no problem playing Rampant Growth on turn two and even though this does not ramp you mana the Spire seems like a reasonable play both early and late. It’s those pesky turns three through five that are the bitch.
It looks like my deck is going to be solidly Naya with only the slightest hint of blue to accomodate Bant Charm and I am worried about the Spire disrupting my curve but I think I will have to see it in action before I pass judgement.
I also have Ancient Ziggurat to fix mana and it also seems like a it can create some clumsy situations. You can’t use that mana to cycle, activate a Panaroma, or anything else that is not a creature. I am very curious what other players experiences were with these two cards.
Another card that I have been wrestling with is the aptly named Lapse of Certainty. Basically an off-color, slightly more expensive Memory Lapse — and old favorite in Limited and Constructed. In the end I decided not to play them since my deck was quite mana hungry. Had I been Bant I would have definitely given them a try.
