Rubick + Techies

Why this works

Setting up kills in lane is pretty straightforward for this pair. A good Telekinesis from Rubick gives Techies a free window to land Sticky Bomb and start charging Blast Off! for follow-up damage and silence. The reverse is also true; the slow from Sticky Bomb makes it much easier for Rubick to land his lift on a retreating target. This basic combination of a disable and burst can be effective at punishing mistakes, but it doesn't create an overwhelming advantage on its own. The two heroes offer a fairly standard kill threat that relies on the enemy being out of position.

As the game progresses, their direct synergy mostly fades. Rubick's impact becomes entirely dependent on finding and stealing impactful enemy spells, a task where Techies offers little specific help. While Techies certainly benefits from a big teamfight spell stolen by Rubick, so does the rest of the team; there's no unique interaction here. Techies will focus on dealing area damage and silencing key targets with Blast Off!, while Rubick plays his own game with Spell Steal. Their plans don't clash, but they don't especially complement each other beyond the laning phase, leading to a typical outcome.
