Poker Dice

I came across a set of Jimmy the Greek's twelve-sided dice, designed for poker. The dice are such that every possible poker hand is possible, and eight stars are wild cards. Three die have two stars, one red and one black. One die has a single black star, and the last has a single red star.
Having eight wild cards obviously makes getting certain hands easier. Does it affect the rarity of the hands? For example, in three-card poker, a straight beats a flush.
