A combat or skill resolution mechanic. Each player draws 5 cards from a 52 card deck. Anytime a ‘roll’ would be required, play 3 cards. May choose 1, 2, or 3 cards from your hand before turning over the remainder from the deck. Add the value of the cards displayed for a total between 3 and 39. 3’s and 39’s are criticals. Draw back to a hand of 5. Reshuffle discards when need a new draw. Optional: may turn in a poker hand of 5 cards for a degree of epic success, being more epic the higher value of the poker hand. Straight flush > 4 of a kind > full house > flush > straight > 3 of a kind. 2 pair and 1 pair are considered insufficiently awesome. The GM should use a 2nd deck for monsters so that player and GM luck is balanced in separate pools. An ace may be 1 or 11. King = 13. Queen = 12. Jack = 11. Optional: Divide by 2 to map to 1d20. Divide by 2 and discard kings to map to 3d6.
This allows for a player to save or build to one good ‘roll’ when they think they really need it.
