That's not how it works.

There's shit with rounding in the NP gain formula that makes Art cards with more hits generally generate more NP during overkill and critical strikes. For everything else have a "worse" or lower hit Art card is superior since base NP gain is calculated off a base class rate (about 1.6% for Casters) then divided by the number of hits of the Art card. So you come up with Merlin's 0.81%. If he had a better Art card, his base NP gain would be docked accordingly, as seen with Servants like Gil. This would make the NP gain of all his other cards worse, so you wouldn't be able to gain like 10+% NP on his Extra.

That said, since Merlin has 3 Art cards it would probably be better if his Art card was better overall.
