Gravity Shield blocks all creatures without momentum.
Lobotomizer removes Momentum.
Shard of Gratitude removes damage from creatures with momentum and Eternity, and makes the deck more safe.
The immortal creatures make the damage, it doesn´t matter if there´s a Turtle Shield or not.
SoG is one of the cards you need for many other decks, and Lobotomizers are quite common.
Should not be too hard to get.
Edit: With catapults introduced in 1.27, and the SoG nerf, this deck could now be worse.
