I think I need to stop checking this thread, following streams, and chasing metadecks. Anytime I go on a losing streak with a deck, I immediately want to change everything up... there is no perfect deck. Why am I stressing out over this?
A good idea is to just avoid netdecking entirely.
I built a Bomb Warrior deck because my first legendary was Doctor Boom, then everyone started running it and it's s'posedly the strongest deck out there and now I'm playing a silly deck I call Dupe Mage (probably has a better name elsewhere).
I will admit it gets frustrating seeing everyone playing the same decks and my insistence on building my own is what causes me to lose so much, but I like that this stuff is a work in progress for me.
Like I wanted to play a Lucentbark deck because I like Druid and it seemed like it'd be unique, yet when I first built the deck and tried it out I lost basically all the time. So I identified what wasn't working - in my case the early game was so bad that I'd be so behind by the late game that coming back was almost impossible - and compensated for it, turning my Lucentbark deck into this weird thing where I use cheap tokens and buffs to get board control early on and then duplicate Lucentbark to create a wall of minions that's almost impossible to get through. Thanks to that legendary that gives you both spells when you choose either, it's actually not that bad. Decent value, plenty of heals and a nice wide board kinda works.
The next deck I want to try out is one built around Rafaam. I was playing against such a deck earlier today with my Bomb Warrior for a quest and it was like a little light bulb went off in my head when my opponent turned the six bombs in their deck into legendaries for them to use.
I think with a suitably strong deck, Control Warlock is going to hard counter Bomb Warrior. Could be fun to experiment with.
