Well Druid is tuff to kill. Killing her fast might be easier than trying to go for a longer game vs her.
I think Grimbart did a pretty good job with the Ehren, Mhgeeden and Grimson.
An old school FM with some durable creatures like Necropian Vampire and Grizzly might still work.
You could you any mage with a strategy like that i guess.
Equipment Warlord wouldnt be a bad choice, even if thats what your trying to avoid.
BF 3-4 creatures, wands and Balista.
BF is pretty good and easy to use.
With the Druid id expect Vine Tree 4 Thornlashers, 4+ other plant creatures and ~ 4 other creatures including a Grizzly or two. Its hard to kill all that.
Both Warlocks should be ok if they have curses and or attack spells and a few durable creatures.
Druids often go unarmored or really low on armor early because they heal so well.
So a few curses and attack spells or WoT or a few good creatures and then 6 poison blood and Deathlock might just do it.
Still im a Druid player and id likely rather be the Druid than the opponent.
But i like long games and don´t get bored easily
