So... initiative 7 in Kardor....
I suppose green ones?
depends on how many stacks and how many dragons in stack. Anyway, try to use trap (to prevent them to hit you in first turn. If they are greens, then put trap 2 hexes from your unit because they usually trying to use their ability to drag your units and hit them). If there is one stack then use trap+dragon killer spell (as a mage you must have talent to cast 2 spells in round) to your unit with most damage. Try to change cyclops for knights (they have increased damage to dragons). Sorry, but for more info more info from you is needed
