Phoenix + Tidehunter

Why this works

Catching multiple heroes with Ravage creates an ideal window for Phoenix to use Supernova. The long stun from Tidehunter’s ultimate holds enemies in place, preventing them from attacking the sun and making the rebirth almost guaranteed. This secures a secondary stun and deals heavy area damage while heroes are disabled. Even outside of that perfect combo, Tidehunter’s presence is a huge help. His general tankiness and the attack damage reduction from Anchor Smash make it much harder for opponents to focus down the Supernova, giving Phoenix a better chance of survival even if Ravage is on cooldown.

The threat of this ultimate combination forces opponents to play spread out, trying to avoid a fight where they are all grouped up. Their main counterplay is splitting the map or trying to get a pickoff before a fight can begin. If Tidehunter finds a good initiation, Phoenix can follow up from a safe distance for a very effective result. Enemy cores will often need to buy Black King Bars to deal with the control, but this pairing can still be a problem. Tidehunter disrupts physical damage and Phoenix can often outlast the magic immunity with Sun Ray, making them a difficult duo to handle in mid-game teamfights.
