"When Wolverine attacks alone, double your life. This effect cannot raise your life to a value higher than 10."
If you have 8 life, and Wolverine attacks alone, what is your new life total? 8 doubled is 16, but this ability cannot raise your life above 10. Is your new life total 10? Or can you not use this ability unless your current life is 5 or less, where doubling it would not increse your life above 10? Thanks.
