I created a f2p account for fun and am at ranked one just saw the nerfs. I played budget versions of watchpost rogue and control warlock my legendarys are kargal, jandice, and pokelt. Should I disenchant jandice and pick a playable deck for the free deck. I looked at the free decks and they all look OK at best
I'm having pretty good success with budget warlock on my f2p account. Got the free warlock deck so the 2 cost legendary and opened a rustwix. Pretty much rest of the deck is core, common and rare. Still missing a few cards that u think would help, but crushing a lot of meta decks right now. Running the 6, 7 and 8 mana taunts and jaraxus with flesh golems (got those for free too) and a few control tools. I doubt it will get too high in rank (the soul shard legendary would be a huge boost probably), but I dont see too many bad matchups for it. Has a decent amount of early game removal/aoe and watchtowers to try to stall things out until turn 6, and a lot of big mid game threats/taunts into jaraxus.
I'm still trying to find ways to improve it with my budget, but I spent about 1.5k dust to build a wild paladin deck for easy legend and all those rewards.
Warlock is the best class early on because the hero power makes it so you don't exactly need synergies just good cards. Hunter is tradionally a very cheap class to start building because a lot of the time the aggro cards are commons.
