So what's the balance issue?
From my perspective you'd be using this for Silver level of play, which means you need to cut the Ulis and Aether Pends as they make the whole thing very unreliable. Purify is meh in Silver/AI4, Leaf Dragons have literally no place here, 3 Staffs is 1-3 too many (which frees up 3 more cards in the Animates) and you don't have enough Spectres to draw offense reliably. In other words, you need to focus the deck considerably. Yer healing too much for farming since speed = electrum/score, and it'd be a lot stronger as an Octopi+Spectre deck with the Shards still there.
If you want EM's, you can keep 2 Staffs and pack 1-4 Heals. If you want it stallier, you either need to switch to Permafrost Shield or get better healing for Thorn Carapace to work its magic as well as more CC (more Octopi/Squids work).
Advice will differ depending on what you want to farm, so specify.
