I read a post on how to best train your fighter and it said that gray and yellow abilities are expensive and rare and save these abilities and use purple and orange abilities instead.

Why are gray ability cards expensive? Don't we get more gray ability cards when we open training pack like 4 gray and 1 purple. And gray abilities don't really affect the damage of a fight move than purple or orange ones that's why purple and orange abilities are more rare. When we open a h2h reward box we get more gray and yellow abilities than purple and orange. Gray matching ability of 4 or 8 xp will give 20 or 40 xp but purple or orange matching ability of 30 or 40 xp will give 150 or 200 xp.

Why is it advised to save gray and yellow abilities and use up purple and orange abilities while training a fighter? Can anyone explain?
