This is a series of cards similar to the nymphs. Their common trait is that they all involve how many cards are in your hand at the end of your turn. I'm stumped for some of the elements and I'm sure most of the ones I've come up with need reworking. Important note: this is about the abilities only. Also, these aren't "human" nobles, they are elemental nobles.
Dark Noble/Lord - Your opponent’s attacks have a 1% chance to miss for every card in your hand.
Death Noble/Lord - Deal one poison damage for every two cards in your hand.
Gravity Noble/Lord - Your creatures gain one health at the end of your turn for every four cards in your hand.
Chaos (or Entropy?) Noble/Lord
Earth Noble/Lord - Increase the strength of your shield by one if you have more than five cards in hand at the end of your turn.
Fire Noble/Lord
Water Noble/Lord
Air Noble/Lord
Life Noble/Lord - At the end of your turn, heal yourself for one HP for every card in your hand.
Light Noble/Lord - At the end of your turn, gain two light quanta for each light-producing creature in your hand.
Aether Noble/Lord
Time Noble/Lord - If you have less than four cards in hand at the end of your turn, draw a card.
So, hop to it :-p
