I don't know how many quests I've done, but I have played for 2.5 weeks and received 7 morty cards in that time. I am still very new to Subeta.

i must have been really lucky yesterday - i did all quests x10/without GA (minus sarah/blue room) and got 3, and today i did all quests x15/with GA (minus sarah/blue room) and got 2!
Did 45 quests, got 2 Morty Cards today. One from Library and one from Saggi.

I have gotten a maximum of 3 in on day (all quests but the Blue Building and Fighting quests) I got one yesterday as well.
I typically get about 1 a day.

just tied my record! 135 quests (all quests with GA except blue and sarah) and 4 total morty cards! that's only happened to me once before and i definitely didn't expect it to happen again. 😅 carl, cinthia, alexander, and sagittarius were looking out for my luck tonight!

105 quests today, and 3 Morty Cards. One each from Wiz, Maleria, and Cinthia. Been a while for that. :)

for the sake of keeping track because i've had some pretty interesting runs: day after this post was another 135 quests with 2 cards (both from alexander) and today was another 135 quests with 2 cards (both from saggitarius). i know it's totally random but i definitely feel like some questgivers favor me more than others, haha.

Did 30 yesterday (2 batches of 15) for Wiz and Alex and got 1 Morty Card.
So far have done 45 quests today (3 batches of 15) and have gotten 1 Morty Card. Did another 24 shortly before midnight and got a 2nd Morty Card.
