Hoping to get to 1000 wins in the characters that I have neglected.
Warlock, Paladin, Rogue, Druid and Warrior.
What cards should I look at crafting to make these characters have better win opportunities?
you should check a meta report (for example hsreplay). they tell you which classes have good decks right now and what those decks look like. there are different lists for each archetype, so comparing those lists gives you an idea of what you can switch out without too much creativity on your part.
