Currently, Core + Tome 1 with Tome 2 and WvF to be added very shortly! It not that I unable not build out a Temple type of deck for my tome, it has more to do with time, value and mana costs.
My analysis:
Temple of Asyra: Costs 10 Mana + 2 Clerics costs 10 more Mana to get 2 extra mana a turn and can only be used to summon Holy Creatures. For 10 mana, I can get two Mana Crystals/Flowers out and have 2 Mana for whatever I am in need of. The Spell book cost is 5 spell points vs. 4 spell points for the Mana Crystal/Flower combo. Overall value: Negligible
Temple of Light: Costs 9 mana and gets one attack dice. Each additional Temple nets 1 more attack die. For 4 more Mana you can summon a Knight of Westlock and get 5 attack dice from the start. Overall value: Minimum
Temple of the Dawnbreaker: Costs 8 Mana, the re-rolls are nice, but only are used once per round. Might consider adding this one back into my deck eventually. Overall value: Fair
Hand of Bim-Shalla: Costs 5 Mana, +1 Armor or +1 Melee or heal 1, running a deck with several creatures this card is very handy and would be most likely added back into my deck as it Spell Book cost is only 1. As I write this I am seriously thinking about adding it back into my deck. Overall Value: High
So as you see a lot of thought has gone into the deck and how useful Temples are with the build purposes of the deck. If I had more time, the temples would provide value but when you are dying around round 5 with no heals available you quickly learn that no they are not that useful.
