When in doubt, turn to dota1.
Both tiny+wisp pick and bkb enigma to counter naga are taken from current dota1 scene.
Main difference which I see was Tiny was used to bd together with wisp.Dota1 bd mechanics and invulnerability mechanics are different.
Dota2 is better.I noticed in dota1, twr could still takes dmg even when glyphs are used.
Naga might be new in the pool for dota2, but dota1 shes been there for a while, and ppl already have strats to counter her.
Irrelevant but heres puppey 3 years ago when hes with BFB, together with Merlini, Fear, Kuroky, Demon.(Pajkatt too, but hes not in the pic)
