Mono black aggro is one of my favorite archetypes and Drana, Liberator of Malakir is MBA incarnate.
The best thing about mono black aggro in Tiny Leaders is cherry picking all the best aggro creatures from all of Magic. Every era that had black aggro gives us toys. Innistrad gives us zombies. Khans gives us some warriors. Zendikar gives us vampires. The list goes on.
Then we can take all of that and smoosh it into one deck.
I often forgot Swiftfoot Boots and Lightning Greaves but they can make this deck just work. Turn three haste Drana is gonna be good.
Just like the old Legacy mono black aggro, we can Dark Ritual into up to three creatures on turn one. Or even Drana herself. Either way, Dark Ritual means going nuts and clogging the board.
