I don't have the Lava Hound, so keep in mind this is 1 less than the most expensive deck.

Anyway, about the mirror. Before the update, the most expensive deck had an AEC of 6.9. As seen here:



This is correct. 9 + 8 + 7 + 7 + 6 + 6 + 6 + 6 = 55. 55 ÷ 8 = 6.875. Round this to 1 d.p. and you get 6.9.

Adding the Mirror to this deck (before the most recent update) resulted in the AEC going up to 7.1, as seen here.



Assuming we simply don't count the Mirror, the answer appears to be correct. 9 + 8 + 7 + 7 + 6 + 6 + 6 = 49. 49 ÷ 7 = 7. Round this to 1 d.p. and you...still get 7. What?

However, after the update, adding the mirror results in the AEC going down to 6.3 (as seen here).



Let's try Magma's formula on it.

AEC of 7 cards = 7

AEC of Mirror = 7 + 1 = 8

Total cost to play entire deck = (7*8) + 1 = 57

Average (based on total cost) = 57 ÷ 8 = 7.125 ≈ 7.1

OR

Average (x + 1/8) = 7 + 0.125 = 7.125 ≈ 7.1

What exactly is going on here? Magma's formula, the Total Cost of all 8 cards, and that of just 7 cards (excluding the mirror) all point to the average Elixir cost being 7.1. Before the update, the AEC was correctly displayed at this. But

7.1 ≠ 6.3

So...
