Very nice! Only one thing I am concerned about, which is this: "May be used more than once per turn if flown or endowed."

would get you easy multiple Dive stacks if I'm reading this correctly.
If you fly 2 Reprisals you can recharge a total of twice per turn.
Multiple Dive stacks were what I calculated the balance for in my first post. It will happen but not be a problem.
I didn't realize you had to fly both of them, I figured that the statement in the notes just implied that the ability can be used twice on the same creature as long as you can pull it off. It would be kind of strange and difficult to keep track of if not.
I looked at your calculations but many values there are really estimates for hypothetical balancing and when doing such a complex calculation that makes it very imprecise. I can't tell if the multiple stacks were calculated (perhaps I'm reading it wrong), but with 2 recharges it should hit 24|40 damage. I figured there would be a 2^X somewhere.
To me it just seems the cost : damage ratio is relatively low. The initial required quanta (10
+ 4
+ 1
|
) gets the pieces out, then the upkeep (4|2
+ 6
) hits for 24|40. Another 5
and 1
+ 1 card can get you 48|80 damage for just 2|1
and 2
more upkeep each turn. But I think the most powerful part is that even if they kill your Wyrm, you only need another one for 4
to do the same thing (as it is not a single use buff such as Blessing or Adrenaline).
