?? What's it going to do?! Draw MORE bad cards? I will NEVER understand how time mono works.
This looks like a point of view of a person, who thinks that hourglass is the best
card. I personally think it's a very situational card, mostly useful in duo/trio/rainbow if your deck uses
mostly to speed it up.
In mono time hourglass is much less useful because you have other awesome cards to play. It's not a good idea to make a deck based on super fast drawing of cheap/weak cards because it will rarely win you a battle. Instead make a deck based on halting your opponent so that he can do nothing at all, while your deck develops at normal speed. This works best with quantum denial or healing, so that you can literally make your opponent unable to do anything, but in mono it can also work in a limited way.
Anyway, in my opinion Eternity is way better than hourglass, just look how powerful/useful it's ability is. It's one of the most expensive weapons, with the most expensive skill and the lowest damage of all, yet so many consider it the best of all weapons. That's because if hourglass is the heart of a time deck, an eternity is the brain.
(Thus decks without eternity are zombies
)...
I think the main weaknesses of time are no permanent control (protection would be better than destruction) and a lack of offensive creatures good in mono, other than dragons/nymphs. It's definitely not a lack of good cards.
