Hi, when a card states that : ''All Mi-Gos gain a terror struggle icon'' and the card itself is a Mi-Go, does it gain that icon too ??

I'm guessing that it is ''Yes'' because it would state otherwise that : ''All OTHER Mi-Gos gain a terror struggle icon''

Am I right or wrong on this one ??

Yes, the card grants a bonus to itself. All Mi-Go means every character with the Mi-Go subtype in play.

And remember, unless it says "all Mi-Go you control", then your opponent's Mi-Go also gain the bonus.

Yep, the cards generally mean just what they say. Lots of characters of all types grant things to themselves as well as to others similar to them.

Thank you, that's what I taught but in the same time, it's kind of strange that you get yourself a bonus. Dah well !!

Some cards do exclude themselves and say "all OTHER x get a y" or whatever. But if the word "other" isn't there, they they'd include themselves if they meet the condition.
