I don’t feel strongly either way, but I think Revoke Existence does something cooler, and I don’t run any ways to fetch enchantments.
As I’ve talked about in like three other places now, I’ve tried Consuming Vapors before, but I’m trying it again. I used to like Ashes to Ashes- it’s flexible and does a thing. But in another way it’s extremely inflexible, since it does nothing once you can’t cast it and requires two targets. I’m not sad about this at all, and as I’ve said elsewhere- pretty sure my poor opinion of Consuming Vapors was due to evaluating it in the wrong deck/board position.
The new Blade of the Sixth Pride is also going to make it in, probably for Serra Avenger or Guardian of the Guildpact (Guardian if I have my way, still holding out for that full art Serra Avenger. Only a little bit joking).
Not that anyone is unaware, but it is just nuts how good the spoiled white cards from Mirrodin Besieged have been. I guess when Phyrexians show up, you step up your game.
