The Wall is not a fast deck. It was primarily built to test a theory of indestructibility which I have since debunked. It is vulnerable to very fast decks, especially agro, and to decks which have lobbers.
The goal of early play is to play waking stones with the enchantments necessary to keep them alive against your oppoenent. Extra health, ward, and a resonant helm are highly recommended. Faith duty can be placed upon them, but is better saved for the creatures. There are only three creatures in the deck, and playing them without ward (specifically the verdant veil) is not recommended against most opponents. With the remainder of the enchantments strengthening them and the spell to grant relentless as desired, these three creaures should be able to power through practically any obstacle. A win post turn 25 is common.
