"Double Wing Effect"

[Frank Castle]

Howdy heROes!

I would just like to ask about how the double wing effect works on certain stat boosting cards. I know that it doubles the effect of the card but, what about if you put the wings with cards such as Ancient Mimic? AMC's effect is like in every 18 base luck, you gain 1 agi. If I put that kind of card, will it become like in every 36 base luck, you gain 2 agi or is it still in every 18 base luck, you will gain 2 agi instead?

I would really appreciate it, if someone would give an answer about this noob question of mine.

Thanks in advance. Godspeed.
