Well, this is not the right deck for Skull Shield. Fire Shield is far superior at killing creatures, and doesn't leave skeletons behind which FGs with rewind can take advantage of; because of this, my matchups against Destiny, Chaos Lord, and Osiris get significantly worse. In fact, there doesn't seem to be an improvement anywhere, and yet all sorts of small negative effects keep popping up in randoms matches: Neptune becomes more boring to play against since Skull Shield doesn't kill his Arctic Octopuses quickly enough; Decay plays with Eclipse which actually makes Skellys more of a threat than Pests.
The damage prevention aspect of Skull Shield is not as good as the damage prevention that Fire Shield provides by just killing creatures and removing them from the board.
My idea of using Eternity to mutate enemy Skellys, and then rewind them the next turn so I can Mindgate whatever they became, is, in reality, much too slow to create either board advantage or a hand full of dead cards for my opponent, and it's much less efficient than just bouncing the FG's best creature and copying that straight away.
