Yo people. Any1 followed me before know that i always try to create fun to play and also strong enough to climb decks. I know this meta sucks balls and almost all the decks are shitty boring. But i guess i found the one you looking for.
This control type deck is pretty fun to play and also doing very nice against most of meta decks. Your aoe removals (Warpath, Reckless Flurry, Blood Razor effect and Brawl) totally ruins game plan of many popular swarmer decks such as Silver Hand Paladins, Wisp Druids, Spider Rogues and all other Keleseth minion ones. This one can easily go for fatigue play either.
I'll share more details if this deck draw some attention. Good luck and have fun.
My good dude Kiwiinbacon made a cool video to show how fun and strong this deck can be;
My other dude Kadakk tried the deck on legend ranks and owned a meta Wisp Druid with no problemo;
Mulligan is pretty much same for any opponent. Always keep a Plated Beetle since it's your cheapest early game minion. You can keep a Stonehill Defender as well. You can also keep one of Warpath or Blood Razor against Paladins.
