i mean im pretty sure it is a moot argument because we are both smart enough to realize the obvious pick is a call.banned status in legacycrypt is closer to mishras workshop than ancient tombancient tomb has wheeled before. what is an ancient tomb with variance getting you?
it gives you three mana turn 1 not 2
it is banned in legacy
it is not a valid comparison
with that said i see why youd want ring not crypt, im just surprised it hasnt gotten a mention, that card is the nut in more than just edh
has stone nothing to do with cube. yawgmoth's will isn't a card in the wizard's cube and that card is banned in legacy and restricted in vintage.
you take 1.5 damage a turn every turn (on average) versus 2 damage only when you need to.
this is not EDH/vintage where i storm kill you turn 1 (unless i misread the current list and most of the storm kill cards are all still in). this is also not EDH where random 3 damage is incredibly relevant.
i'm not saying it is a bad card, i'm saying there are many reasons i would not take this card and that it is not as good as you are playing it up to be for your own reasons and other "not valid" reasons.
there are enough times where crypt has outshined sol ring for me that i was just expecting it to get recognition. /shrug
