Ive been trying to get this quest going by playing a couple of games today. Not in one these games have / had last long enough to play one Marin the Manager card, or because of bad RNG when Marin is at the bottom deck position.
I know this event last for another 14 days. But play a whole 15 of Marins cards seems to me a bit too much as the event is on a timer. Anything near 5 would be way more realistic.
Play a friend, set up a deck that allows you to draw cards and/or cheat Marin into your hand. That’s what I did, I completed 13/15 of the quest requirements in less time than it took to complete the first 2/15.
NOTE: (1) The previous 75 pirates quest requires play in ranked mode, but Marin’s quest does not.
(2) Do not overfill your deck with draw cards, as you can fill your hand with cards you can’t really play.
(3) Zola the Gorgon was useful for duplicating Marin. Any “return a card to your hand” will work.
(4) I used rogue. The 0 cost “return a minion to your hand” was very useful. Cleric may work as well, as that class has a few “discover a minion from your deck” or “discover a spell from your deck.” Other classes have similar cards.
