Good reasons. My concern is having it instagibbed by a Lightning Strike, but having 4 shores up a nice offensive option for the deck. Taking 3 a turn is a likely threat, especially if Ethereal Armor Shows up. Which I've noticed is not in ths deck at all. Interesting. I personally feel that Seraph won't pressure an opponent enough without some form of a boost. That was my reason for packing Underworld Connections instead of Read the Bones. Read the Bones is much easier to cast, and even provides instant results on top of a scry. However, in a longer game, Underworld Connections will yield a greater advantage, on top of it being an Aura, and therefore boosting the Eidolons, and enjoying a cost reduction from the Hero of Iroas. Not that you'll be powering out turn 2 Underworld Connections, but a turn 3 Connections could yield you an extra card a whole turn earlier, or be followed up with another potential enchantment.
