Runes provide a cycling-engine so you can find the right circles. They also have an awesome synergy with Astral Slide and Lightning Rift (our only kill-con), so you can lock the table. Counters wreck this, obviously, but it's so cute and a blast to play. Any more ideas to improve this one?

It looks fun :D
You can try Wheel of Sun and Moon, because you need to cycle a lot of cards with Rift in your table to kill your opponent. Many games, you will find that you draw all your deck.

4 Enlightened tutor, to search for the Rune and your SB cards faster would help too.
And Humility always works like a charm with Slice and Dice.

You can search the old rifter decklists and primer for ideas.

No Fluctuator? Free cycling should be good. Also goes very well with the E Tutor idea.

Edit: Eternal Dragon as additional win-con with extra uses wouldn't hurt either.

Fluctuator can't help with Runes and Eternal Dragon is very mana intensive. You need the mana to activate the Rune protection ability.
