Well,
a) Liquid Shadow does not give EMs as of the latest patch, and the health gain is typically negligible anyway.
b) Having cards in a deck as placeholders until you can upgrade them makes little to no sense. While Vampires and especially Gargoyles are powerful cards when upgraded, playing them unupgraded significantly lowers the power of this deck.
c) Yes I have, which served as the main reason for my comments. The deck is too large, making it very clunky, and reducing a lot of its possible power. Besides this, there are several cards in the deck which serve to only make the deck larger, which doesn't seem like a good approach to deckbuilding.
The main problem is that you are trying to use an upgraded deck unupgraded. There is a reason that cards are upgraded, and most decks won't really work at all unupped in this fashion. You are also trying to do too much in a single deck.
