Now that season 55 has started I've decided to try to climb with the deck again and see how well I can do this time around. The changes above will hopefully be an improvement.
This way your opponents will struggle to remove all your threats (think of it as a spiteful deck) and you'll still be competitive against aggro.
Not going wide doesn't mean that your reduced heropower is useless, you still have plenty of ways to buff your board. That being said, don't heropower too much against druid (Spreading Plague), control warlock (Defile), shudderwock shaman (Mind Control Tech) and priest (Psychic Scream)
Most cards are obvious, so I'll just talk about those that are not in the deck and those that might seem doubtful.
One Elementary Reaction is enough.
Grumble, Worldshaker is in the deck to give you an extra bump. It synergizes really well with all the battlecries in the deck, and even if you play it by itself, it's still a 6 mana 7/7 elemental. You can play second Mossy Horror or The Black Knight instead I guess.
Against control, you should pressure as much as you can. They'll struggle to clear your minions, and you won't run out of fuel, which is good.
Against aggro, you'll be fine as long as you keep board control.
Mulligan: the ideal keep is one 4 drop and two 2 drops, because that way you'll curve out nicely (turn one heropower, turn two 2 drop, turn three 2 drop&heropower, turn four 4 drop). You can consider keeping Hex against control warlock and deathrattle hunter, but if you don't know what your opponent will be playing, don't keep it, it's not very good against zoolock or spellhunter.
To give you a rough idea as to what to keep:
I'll write this in more detail in the future.
Winrate, rank and matchups
I tested some different versions, which got me to rank 1. From rank 1 to legend I used version v1.0 (the one with the bonemare and the phoenixes)
v1.1 is when I decided to swap bonemare for elementary reaction and one phoneix for one chain gang. Just one game with this version.
v1.2 is the final version, with no phoenixes. Took me from around #2000 to #321
Getting to legend
Thijs ruining a winstreak :(
Top rank so far
