think these series are a great idea!
And great art ET
I'm unsure about this one as I couldn't see the ability being used often? As far as I'm aware there are no cards yet which have some form of (minor) benefit from being discarded. If you have 
then you're more likely to go for hourglass for drawing card ability :s
I can't say I've followed the discussion on these much, so not sure of other options. What might be interesting is something like, discard one card, your opponent doesn't draw a card next turn, although that would lead to unwanted lockdowns...
Do not compare this to Hourglass. Compare 2x this +4precognitions to 6 precognitions.
It can also be used a draw fixing (although most current decks eliminate the need for draw fixing in the deck design stage. There is a cost for that and this is an alternative.)
That said If you can come up with a better effect, noting that such effect would have to be weak considering it only costs 2quanta and does not cost a draw, then we will change it.
I didn't mean to compare directly as one to one. Just saying that should I have a deck with
and want something to draw cards with I'd most likely choose the hourglass over this (imo).
I'd love to come up with an alternative, and should I, I will post. It's not that I don't like the idea or disagree with it, just looking at the game atm I think this one would be more underused than the other Obelisks.
edit: if you wanted to change the aether obilisk to something like target creature is immaterial for a turn (or something else), this could get the delay effect. "slow down time" kinda slant on it. Not saying that's a great solution, just a thought.
