Unstable Hourglass | Broken Hourglass

[OldTrees]

so a 7 turn win with 1 in your starting hand? and it's basically unstoppable. you can't ever get rid of this card....

No.
4 Pillars|Towers + Unstable Hourglass | Broken Hourglass results in a turn 17|14 win. This is delayed by 1 turn if you only have 2 pillars.

Steal destroys and copies.

Except that if im not mistaken steal has a built in destory effect and therefore you simply end up duplicating the card.
The card as is can only be temporarily countered(at best). Soft CC, or a steal that ends in it having to be played again.

huh. but with precogs and stuff you could speed this up no problem. also, 2 of these in a deck seems like you can never deck out if you have the time quanta for it.

Then it would not be merely the hourglass as your shocked statement described. I do recommend to continue to try to prove it OP. (hopefully with some math involved)

2 Unstable Hourglasses + 5 per turn > Eternity + Photon + 3 per turn = anti deckout

True in most cases, but keep in mind that, barring extraordinary SoSe, a 6Eternity/6Sanctuary/6 PA 60-card deck can still be outdecked.  A deck with two of these, however, needs only a single PA'd sanctuary and then it cannot be outdecked.

no deckout. great.

Both need a PA's pillar stack (4 pillars > 2pillars).
Both need a single PA'd Sanctuary.
Eternity uses 2 Eternities (to prevent eternity being the last card) + 1 photon + 1 PA
UH uses 2 Unstable Hourglasses.

Total:
Eternity: 3PA + 2 Eternity + 2 Time Factories + 1 Sanctuary +1 Photon = 9 cards
UH: 2PA + 2 Unstable Hourglasses + 4 Time Factories + 1 Sanctuary = 9 cards
Both can be outdecked by 1 method: Shard of Bravery.
Eternity can also be outdecked by Antideckout + Voodoo Doll + Freeze.

Incorrect, no?  Eternity needs 3 Time Factories to prevent deckout, and UH need 5(play cost = 4, ability cost = 1).  Equivalent card cost, and UH cannot be outdecked by voodoo freeze or ice bolt freeze. 

EDIT: Never mind, I think you assumed mark of Time.  That would change things.
