As I understand the text, these re-rolls are bought for the whole game.
Even 2 re-rols each turn make great advantage and can breack balance, turning comanding into hazzard of re-rolling rolls.
If it`s a limited chance to challenge the luck, I find it interesting and worthy.
But only official game-makers can make it clear.
My own oppinion is a gamer`s oppinion.
