Phoenix

Icarus Dive, Sun Ray while moving and Supernova destroy trees.

Make sure to land most of the Fire Spirit and get extra right-clicks in or deny a creep here and there.

You can attack once during Icarus Dive.

Fire Spirits provide short lasting vision so you can scout pillars for wards or Roshan pit.

You can use Sun Ray to escape over cliffs and pillars.

Supernova always turns night into day which can be great against Night Stalker for example.

Your allies can deny you in Supernova when one hit is left.

Avoid placing Supernova close to opponents' counters. Use terrain features to allow Supernova to go off.

Phoenix is great at defending towers with his long range damaging spells and escape.

When not much is happening, push out the sidelines with Fire Spirits and Sun Ray without even showing yourself.

With Aghanim's Shard, use Sun Ray before Supernova as it will persist and will be refreshed upon explosion.

With Aghanims Shard, use Sun Ray during Supernova on enemy heroes hitting your egg to have more chances of survival with the miss chance.

Look to go on Phoenix when Icarus dive was used. It has long cooldown.

Fire Spirits are Phoenix's main laning spell - Look to dodge them by moving chaotically.

Phoenix's Sun Ray does a lot of damage against high HP heroes. Run away from it or make a sharp turn.

Against Phoenix's Supernova you need to decide very quickly if you want to fight or run away.

Avoid fighting in choke spots and clumping up against Supernova or Sun Ray.

Spell immunity and magic resistance items are great against Phoenix's magical damage.

Attack speed items allow you to destroy the Supernova faster.
