My results are very inconsistent. Unless I get Warriors so I can build around their tanking ability, I'm not really sure what to go for.
I've had somewhat decent results by taking inspirations from RPS builds posts (last one:
Dota Underlords builds [August Update] – 7 best builds for Mage, Knights, Trolls, and more).
Though, they are more of a wishful thinking, seldomly applicable to real case scenarios, as they imply getting all the right units at the right time and most of them complete their synergies at level 10 with several 4* and even one 5*.
Though, the ones I have most fun with are:
- Assassin/Scrappy: it only really makes sense if you manage to get some inventors to tank ASAP, or you'll be wiped out easily by beefier enemies. Since the RPS suggestion relies on three 4* (Templar Assassin, Sand King, and Alchemist), I usually replace them with more inventors (I love Tinker!), and use different assassins while I hope to get the right ones.
Also, the mighty Slark with Mask of Madness is always fun to watch.
- Knight/Troll: not always viable, considering how coveted are both knights and trolls, but still!
I really enjoy the trolls' attack speed buff, it's sort of gratifying to see my heroes hitting crazy fast.
I'm not a big fan of knights, usually, as in general I don't like having to hope for my units to position properly, but they have a nice synergy with trolls, so
But to be honest, I'd always play full bloodbound with multiple big-time contracts, as seeing your heroes grow huge is just super fun.
(Yes, I love for-fun glitchy builds, and I was super into the Arc Warden + Crystal Maiden combo, with AW multiplying endlessly, before it was patched out
)
