WoH questions

Still trying to figure this thing out.
Is it better to have more white cards or less green or blue cards?
a white punch deals 2 damage & stuns for one round
so 2 white punches you can deal 2 damage to 2 opponents and stun each for 1 round - total 4 damage
a green punch(which uses up 2 white) deals 3 damage & stuns for 1 round
Also is there a help somewhere that lists what all of the icons & numbers on a card mean
Thanks!
