so i just got my first MM booster
(le simon williams, rookie wonderman, vet snowbird, rookie wildchild) and an earthquake
please help me understand how this card works
it takes away 3 clicks from every character without a wing symbol
is this every turn?
if no, can i feild more than one of these cards? would this card not be a beast with a team of all fliers?
if it KOs someone, do i get the points

At the start of each players turn, that player rolls 2 dice.
If the dice come up with a total of 2 or 3, 3 damage is dealt to each figure without flying in the game (this is damage so it is reducible by powers like Toughness and is able to be transferred due to Mastermind, but it's not an attack so Super Senses wouldn't let you avoid the damage).

Once the Earthquake "goes off" (for lack of a better term), it is removed from the game and you don't roll for it anymore.

It is a Battlefield Condition, so unless you're playing with special rules, you can only use one of them (however, you're opponent could be using one too, in which case you'd roll twice at the start of each turn and the Earthquake could "go off" twice (once per card)).

If it KO's a fig, you get the points so long as you have damaged the fig with one of your own characters...otherwise I'm not sure.

i thought that your opponent rolls for the 2-3 to get the card cancelled?

Nope...that wonderful little colon after "remove this Earthquake from the game" makes it so that the Earthquake only causes damage on the field if the removal conditions of rolling a 2-3 are met.

Also, both players roll before each turn...not just your opponent.
