When you summon a mana crystal, use harmonize you get the mana increase so its ready to USE the turn after.
Big difference imo.
Did you mean spawnpoint? You can't use Harmonize on mana crystals right?
Well, this is my best attempt at a Priestess spawnpoint opening. I think it is doable, but I also suspect it can be shut down effectively, especially with early zone attacks.
T1: 20 mana, Temple of Asyra+Harmonize, 6m
T2: 16m+2 (on Temple), clericsx2, 8m
T3: 18m+2, Staff of Asyra+ some armor, 3m+4 (the clerics pray)
T4: 13m+6, Temple of Light+Gauntlets or Leather Boots or face-down enchantment, 1-2m (+8)
T5: 11/12m+10, Valshalla+attack, 0-1m
The clerics have prayed two times at the temple, making their effective cost 3. They should now be considered Blocks that happen to power Valshalla when they die. Opponent will still be ahead, but two daze-chances and Valshallas stun-chance will hopefully buy some time.
