My own thoughts from being a huge aggro fag who desperately tries to make aggro work against various playgroups, to varying degrees of success.
I did have good experiences with Aurelia. She can threaten very fast kills, especially paired with shit like Hero of Bladehold, there's a good aggro (control) toolbox to be found with Sunforger, and Final Fortune finishes catch a lot of people unaware. The recent Helm combo adds a lot without detracting from the core of the deck. It's just a free one-card combo with your commander. No deckbuilding concessions whatsoever.
I have also tried Anafenza hatebears, I figured it would be better, but I'm probably not doing it correctly. Deck scales pretty badly against multiple opponents. I have included some obvious Reveillark 'n friends combos in there, with Survival of the Fittest and others to tutor them up, but my combo elements are actively struggling against my hatebears elements. They don't merge well. Whenever I play it I think I'd be better off going full Boonweaver / Hermit Druid / etc. combo. Anyone had luck with low to the ground "Hatebears" strategies?
