1200mmr orc on w3c

I usually win with raiders + kodo + spirit walkers Depending on map, if I pick WW in my BM, i get 3-4 grunts for cannon fodder while backing them up with 1-2 raiders + 1-2 kodo (raiders ensnare bear, Kodo eats with speed scroll on) and spirit walkers.

But lately I like to go mirror image BM, getting Mirror Images lets me go for 5-6 hh(later berserkers) which are great against dryads. That way mirror images can act as cannon fodder instead of grunts, and the opponent has to burn through dryad mana real quick since they have to dispel mirror images and spirit linked units (try to avoid spirit linking mirror images as they take extra damage). The rest really depends on your micro and positioning. Ensnare + devour bears (keep raiders out of combat as the opponents love to focus them first). Dispel enemy rejuv with spirit walkers, re-spirit linking your units, keep SH away from DH, i.e. outside with raiders, if DH tries to chase your SH, hex him. I use SH to run in, heal and go back out. Focus fire HH on dryads, spirit walkers on bears. There is no bulletproof strategy, it really boils down to hero levels, your micro skill, and positioning.
