I like most of the ideas, but I would question balance.
Chronoton | Age Elemental - Too much chance to spam them with fractal. Even with a 60 card deck, 1 turn with 6 of them, which would not be hard with fractal, is a tenth of the deck, which is pretty big for a single turn. I think its just a bit too strong of an effect to be on a card so cheap.
Sands of Time | Sands of Time - I guess it would be expensive, but, still, the effect is pretty big. I would say maybe a spell, and it would be ok, so its one use only. The fact that it requires time and death helps balance this.
Life Cord | Life Cord - I actually really like this, but, again, I think it could use a bit of balance. It would, however, make a great card for stall decks.
Clockwork King - A bit light nightmare, good synergy with dune scorpion, yes, I think this one sounds pretty good all in all.
I like the idea of forcing discards, something stall decks could certainly use, but the cost would need to be fairly high. I would love to see more of this, as discarding is something that would likely really help the game, as a whole.
