New (Year's) Resolution: Blackjack?

This is my second entry into the  New Year’s Resolution Mechanic challenge by Prismatic Wasteland! And honestly this one can hardly be called new as it’s really just blackjack with a single twist… Oh well!

Stats

The stats don’t really matter. For this example we’ll use the ol’ reliable Brain and Brawn, for mental and physical tasks. Then simply assign a measure of how good a character is to each. For this we’ll say you have anywhere from 0 to 2 in a stat.

Play

When a task needs resolving first determine the most applicable attribute, Brain or Brawn. Draw a number of cards from a standard playing card deck equal to that Stat. Note the highest result of the cards drawn, with faces and Aces equalling 11.

Reshuffle the cards back into the deck. and begin playing blackjack, you vs the Game Master. With the exception that your new cap is 21+ the highest result drawn from your Stats.

Example

Notes

 As the example shows once you get over 21 you are guaranteed the victory, I would suggest if you meet the cap exactly it is a “crit” Incentivize players to risk busting but more importantly if the GM gets 21 their win beats yours.

I also think the stat bonus is too generous for my games so I would consider giving a GM a “difficulty bonus” to compensate. This could be card draws like the stats or flat bonuses to the GM’s cap.
