Quest paladin obviously

You already know what I’m about to say so rather than rank about it… a quick easy fix that probably will solve a portion of the deck is
Either
A. Increase the murloc requirement to 7-8 which slows down the deck quite a bit but keeps it competitive with how many times they can flood the board
OR
B. Change the text to instead of How many SUMMONED murlocs this game to how many PLAYED murlocs
That significantly decreased the time it takes to finish a repeatable quest but with how much you can generate murlocs it shouldn’t be an issue
It should also be noted that this will also decrease the number of times they can complete the quest which should be a positive not a negative

They should have tied the quest to something other than murlocs so there is a deck building requirement. Like “play 4 holy spells, your summoned murlocs get +1/1”

That way they had to think about their plays and what to include in their deck instead of just jamming murlocs and getting quest rewards for free

That also makes the deck more interesting with more room for creativity. You could just run a couple brews and go wide with less buffs, or run a more substantial holy spell package and go for a taller board with chunky murlocs

i think the quest is fine
but braingill…ive lost many games because they were able to refill their hands thx to braingill
