One of the deadliest things I've ever found with the Protoss: The Reaver Recall. Really late in a game, when you (as Protoss, of course) have Arbiters with Recall and lots of Reavers, you may want to try this strategy.

Create a few Scouts with Dragoons and Zealots (along with those Arbiters and Reavers). These few units will be a distraction force. Make sure you have at least 4 Arbiters hotkeyed sepretely so that you can easily cast Recall if they start dying. Clump up those Reavers into a small area in a safe place inside your base.

Position your Arbiters to the side of the enemy's base and your distraction force at the entrance. Tell your distraction force to "move" through the enemy's defences at the same time you are telling your Arbiters to move to their peon lines. If done correctly, the enemy's attention should have been directed to your distraction force while at least one Arbiter made it to their peon lines. Tell those Arbiters (when they're at the peon lines) to cast Recall on the big clump of Reavers in your base. If done correctly, the enemy should suddenly have tons of Reavers inside their base blasting away at their peons.

The only drawback to this strategy is that those Reavers can't fight off air units. Recall some Dragoons, Scouts, Corsairs, and/or Archons along with the Reavers to prevent air units from picking off your Reavers. And if you're feeling REALLY evil, recall a Probe along with your forces and start connon rushing from inside their base! (Make sure you're not fighting Zerg if you try that, because you can't build your Pylons and other buildings on Creep)

Make sure you tell your Reavers to build lots of Scarabs long before you even attack with the doomed distraction force.

Tips for this strategy:

If you know you're fighting against an expert player, try this for your distraction force to make it seem more like a real attack: 6 Zealots, 2 Dragoons, 1 Dark Templar, 1 Reaver full of Scarabs, 2 Scouts, and 4 Corsairs with the Disruption Web ability.

It helps if you're playing on a money map like Big Game Hunters.

A very helpful thing that you can do to help get those Arbiters through a heavily defended base is that you can make 2-4 Scouts escort the Arbiters. The base defense, like Spore Colonies, Photon Cannons, and Missile Turrets will probably attack the Scouts rather than the Arbiters.

Other mean things you could do with this Recall strategy is to Recall Dark Archons along with your other troops (Like Dark Templars, Archons, Carriers...). That way, if they have lots of mobile defence, you can just cast Maelstrom on their forces. Or, if you're feeling REALLY, REALLY evil, have 1 Arbiter inside their base and 1 inside your base. Use the Arbiter in their base to cast Recall on a Dark Archon, and while the Dark Archon is inside their base, cast mind control on one of their peons (If they're Terran or Zerg). Then you can just clump that peon, the Dark Archon, and the Arbiter that was inside their base and, using the Arbiter inside your base, Recall them all into your base. You should now be able to do things like Siege Tank/Archon rush. This WILL scare the defending human players badly. Also, if you mind controlled an SCV, you could have Medics behind your line of Dark Templars and Zealots (that's just pure mean).

I hope this helps you play as Protoss!

CreepColony's Opinion: This requires a lot of micromanagement, not recommened for newbies.
