This deck is pretty straightforward to play and is currently winning ~2 out of every 3 games I use it in Masters. But most important, it'll confuse your opponent to no end because half of these cards haven't seen the light of day in over a year.
It works about how you'd expect it to: play elves, put elves in your void, bring them back with Zende. I usually save Grasping at Shadows to bring back Acantha at key moments, but using it to refill your board when you have Zende in your void is also a good option.
If you're looking for ways to reduce the shiftstone cost of this deck, you can swap out Tavia for any other 2-cost elf -- she's good in the deck, but not good enough to justify crafting if you don't already have her.
