I only managed to upgrade 3 Shard of Gratitude so far.
I have 17 Quantum Towers, 6 Supernovas, 1 upgraded Pulverizer, 3 upgraded Quintessence, 1 Jade Shield, 1 Permafrost Shield, 6 Electrum Hourglasses.
I do not have Lava Destroyers, no upgraded Protect Artifact, no Improved Antimatter, no Improved Heal, no upgaded Aflotoxin.
Would this deck work within these limitations?
Perhaps change 1 Pulverizer to 1 Eternity & add 1 Photon to avoid deck-out?
