Reggie, I don't think the wording on those cards are correct.
I'm not 100% certain what wording would be used for Leader's Guidance (probably something along the lines of "If there is a Diancie in play"), I'll have to check later, I do know that Diamond Cutter's wording should be:
"Diamond Cutter 40x
Does 40 damage times the number of Carbink and Diancie you have in play."
or
"Diamond Cutter 40+
Does 40 more damage for each Carbink and Diancie you have in play."
I saw you entered Diancie for the CaC contest. Oops.
