wisp+ursa, ultimate ganker. Opponent cannot farm alone.
Dark Seer+Axe, bring down tower in less than 6 min plus killing opponent hero. Surge and shell axe, then let axe chase ppl.
warlock+windrunner -fatal bonds+powershot(on creep and hero). I also dunno how to count the total dmg to hero.
Naga ulti+sk ulti or enigma ulti(after they ready, naga off ulti)
