Situation in which i struggled to determine who was correct

[boomshay]

Hello All, I'd like to thank anyone who takes the time to read and answer my questions in advance. I'm very new to the game (3 games in) and absolutely love it so far.

Scenerio: (may be a bit fuzzy on details because I don't have the cards memorized yet)

Will is in combat with a monster that does +4 damage to elves (which he is)
Mike plays the card that allows him to steal the battle and fight it himself.

Mike specifically asks everyone what combat level he needs to be at to succeed, everyone answers the base level not including the +4 to elf because they didn't see that Mike was an elf as well. All opponents missed this and Mike didn't bring it up; so he won the battle.

A few rounds later Mike tells us because he wasn't sure if it was legal or not.

So, munchkinly maneuver? or Cheating

Thanks,

booooooom
