You're making this really difficult.

Okay, anyway, I'm pretty much giving away the answer here:

"A weapon stout" -CLUB

"a priceless jewel" - DIAMOND

"The beat of life" - HEART

"a farmer's tool" - SPADE

Ok, a poker game... Goddammit to hell, how could I not have made sense of that before your dead-giveaway-ass-clue?

I'm gonna go by the assumption that I got it right and drop the riddle that I have been sitting on for a week:
First seek the man who wears a disguise,
who deals in secrets and tells naught but lies;
Next pray tell me what's the last thing to mend,
the middle of middle and the end of the end;
Then, if you would, please seek a sound
that is one utters when an answer is nowhere to be found;
Bring it together and tell me this: What is a creature you would not want to kiss?

Hate to burst you bubble, but not exactly correct.

The correct answer I was looking for was "A Pack of Cards".

But close enough, I'll accept your answer as correct (since you already posted your riddle).

This is how the rest of the clues play out:

A dozen Royals gathered round - 12 Face cards (4 Kings; 4 Queens; 4 Jacks/Knaves)

Entertained by two who clowned. - 2 Jokers

Each King there had servants ten - Number cards (Ace to Ten)

Though none of them were also men. - (Number cards have no faces)

The lowest servant sometimes might, Defeat the King in a fair fight. - Ace can be the lowest card, and the highest card depending on the game eg. Blackjack
