I tried this deck out and did not have the shards; Instead I used 2 Feral Bonds and a Deflag.
Thanks to how fast and well it worked, I now have 2 Shards of Gratitude, 1 Shard of Divinity, and the odd misc weapon or creature.
Thanks for the tip on this deck.
Things I noticed:
With 4 Otyughs I usually have a high chance of getting one out fast in this slim deck.
Keeping the Deflag helped on occassion when a Pulverizer would just refuse to show up.
Surprised I didn't miss the boneyard; the life Quanta had to be handled carefully but still worked out just fine.
Great deck.. I used with good success on the easier FG's, could farm top50 with good success, A5 Elemental Mastery wins except when the regen cards drew last or just lost due to a bad draw.. easy wins mostly too.
