Let's just hope they're good and not...
-Beat 8-5 Lunatic with four dragon allies; 0/1 time (All shall fall to the Falchion)
-KO Lvl 41+ Foes with Armored Units; 0/15 times (Yes, there are indeed units higher than level 40 according to the March quests)
-Complete a 7 chain bonus only in Adv. Arena Duels; 0/10 times (Did you hoard your dueling crests?)
-Clear tenth stratum using only 3* units or below; 0/15 times (If someone did it, you can too!)
-Defeat Lvl 40+ Ryoma; 0/30 times (Cause Ryoma felt like it)
And finally, a quest that everyone can do no matter what...
Of course I'm over-exaggerating but I wouldn't be surprised if they revealed completely disgusting quests just as an April Fool's joke.
