Monster cards

Some monster cards seem to be level-restricted, much like meso/equip drops. I noticed this when doing Sakura castle (or whatever that castle with the toad final boss is called) on my bowmaster and xenon.

I first did it on my bowmaster (200), and merely assumed the cards did not drop, and doing all the quests, I did not find a single card. However, while doing it on my Xenon, I noticed monster cards dropping for all the mobs, so I went back to check my Bowmaster to see if I had the cards already. I did not, so I'm thinking that it might be level restricted, though it would be great if someone else can confirm/refute this.

And if such is the case, is there a way to still get the cards on my Bowmaster?

If you're talking about the stuff like chunin, jounin, tonosama, red samurai, I got them on a 200+ xenon last week.
