i tested a bit with 1.29, and if it arises during war, immophoenix-decks are really weakened.
still, we have to find a good mixture between rush-decks (graboidrush, immophoenix, immogolem, ...), bolt-decks (sanctuary-bolt, poison-bolt, sundial-bolt?, ...), lock decks (i like shield-locks, maybe not easy to prepare, against us), and some really unexspectable decks, like antimatter-phoenix, adrenaline-eaters, etc.
