@Bilbofilter:
Thanks for the congratulations, I'm glad you enjoyed the report and these posts.
Akiro's Favor is a card I'm pretty excited about. One of the things I immediately thought to do, and almost made it into The Aviary was a Sosruko, Ferret Companion + Akiro's Favor package. My thought was that the mana was worth spending against most solo mages because the ferret could put them at a huge action deficit. Andrew talked me down from this plan, pointing out that enchanting Sosruko now made a 10 mana target that could easily be killed by a single Flameblast or Perfect Strike. I'm pretty leery of setting myself up for trading down mana, so I backed off the idea.
In retrospect, I think I would have very much liked a Sosruko against Nick Tinko's Fire Wizard, possibly against Andrew's Forcemaster, and likely vs. Harry's Warlock. Being able to waste a solo mage's main action, and possibly stop them from moving is very, very powerful. What I don't think I realized was that Etherian Lifetree is just as helpful to the ferret as to the falcons. I wouldn't always play lifetree just to support Sosruko, but if I had a lifetree, it becomes reasonable to enchant the ferret due to his increased survivability.
As far as bats go, I like them, particularly against high armor opponents. Andrew and I seriously considered including a few as "falcons 7 and 8". Getting to rot through armor can cause a lot of trouble, and tax people's condition removal resources. However, I don't very much like the idea of enchanting them, as a 3 point enchantment is a big investment on a 5 point bat. For just two points I could get another bat, which will double my rots, instead of increasing them by only 50% and putting a lot of eggs in a tiny basket. Enchanting a Tegu makes a bit more sense to me, a third of the cost of the animal for 50% more rot sounds good if what you want is more rotting.
Edit: I feel where Akiro's Blessing is really going to shine is the near-solo mage who is relying on a lot of Burn/Corrode/Stun or can't afford to have below average damage dice. Probably a Warlock, Forcemaster, or aggressive flavor of Wizard?
