Here's more of my 2 cents on the cards discussed here.
Wall Shift: Very limited, but sometimes useful, too expensive for me to play.
Battallion of Fear: Excellent for a resource building / delay strategy (which I'm quite fond of) and it simply wins you the game often in these situations.
Centaur Trainer/Stonehenge: Useless except as a beast keyword.
Demolition Troop: Very limited, but occasionally.
Tubular Bells: Flat out amazing, in every deck I make, demolishes in early game, demolishes brigand opponents, or people who destroy your facilities.
Dainai Present: Limited, though it will often save your life, also, limited combo usage for a kill.
Earthquake: Limited but can be powerful in the right offensive deck.
All Elemental Attack: A -Much- weaker version of the other convert to attack cards, nearly useless.
