THROWDOWN 2 FISTED POKER 21

This game was recently brought into my casino and was wondering if anyone knew what the house edge on the bonus bet was. The basics of the game are:
- standard blackjack rules
- must play 2 hands
- with the 4 cards from the 2 hands you make a poker hand getting paid like so:
pair of jacks or better 1 for 1
trips 4 for 1
two pair 6 for 1
flush 8 for 1
straight 10 for 1
four of a kind 75 for 1
straight flush 150 for 1
four of a kind suited wins the progressive

- players can play from 1 to 10 dollars on the bonus bet. The minimum 1 dollar bet qualifies them to win the progressive.
- there is 5 "squares" on the table so a maximum of 10 hands could be played.

My first impression of this game were not positive, but then again I thought that lucky lucky was a really bad bet as well. Imagine my surprise when I discovered it's one of the best bonus bets for blackjack.

So if anyone knows the house edge on this bet, or could figure it out I would really like to know.

The web site mentions that "Lucky Player" pays 5 for 1 and "Magic Card" pays 20 for 1. How are these hands achieved?
