What is the best replacement to aya blackpaw in this deck?

IMO, you don't play any jade deck without Aya.

Just like you don't play rogue decks without a legendary card like quest, edwyn van cleef or Sherazin, Corpse Flower. There are no replacements since the whole deck is build around these cards.

You can go with spirit echo as it might provide more jade cards, else it will still be a good card paired with defender, thing from below, dopplegangsters.

Jade Spirit

Aya is not really so important in this deck, i was running thalnos and lighting storm instead of Aya and 1 devolve, and i got from 15 to 5 rank in 2 days,
Edit: I also tried Jade spirit, but it was pretty bad, too slow and hard to play, so then i placed thalnos and it's a lot better.

Is this not the same as below deck?

2 mounths in row to rank 5 with this deck...

Went rank 15 to 10 just today. Has a good chance against pretty much anything... murloc paladin, secret mage, pirate/taunt warrior. Gotta get good draws against quest rogue, though.

Edit: made it to 5 now. 15 to 5 in less than 2 days.

Missing:

1x Mana tide totem > 1x Spirit echo
1x Primafin totem > 1x Lightning storm
1x Aya > 1x jade spirit

Any recommendations to swap my missing cards to instead?
