The Archon Toilet refers to a Protoss tactic unique to Wings of Liberty that combines the Mothership's Vortex ability with the Archon's high splash damage output to destroy large groups of enemy units quickly.
The effectiveness of this tactic was significantly reduced in Patch 1.3.0, which made units leaving the Vortex invulnerable for 1.5 seconds. Even so, it remained a vital tactic against Broodlord-based lategame Zerg armies until the release of Heart of the Swarm, where the Vortex ability was removed completely and replaced by Time Warp.
When engaging a large opposing force with the support of a Mothership and Archons, cast Vortex in the middle of the largest group to "flush" the group into the Vortex. Then order your Archons to move into the Vortex as well. Upon the dissipation of the Vortex, the Archons will attack at once and the resulting splash damage will likely destroy all enemy units hit. High Templars with Psionic Storm can also be used in lieu of or in addition to Archons.
- Squirtle Vs. Mvp - 2012 GSL Season 2 Code S Final, Game 5 (Metropolis) (Official GOMTV Series VOD). Unique both because it came in a GSL Code S final and because it was used to take down a large fleet of Battlecruisers. Combined with a Void Ray transition and Psi Storms, it is hailed by some as the best moment in a StarCraft II pro match.
- Brown Vs. LosirA (KangHo) - 2011 GSL November Code A Round Of 24, Game 1 (Daybreak) (Official GOMTV Series VOD). Defeated a force including over 15 Brood Lords and swung not only the game but also arguably the series.
- KiWiKaKi Vs. Stephano - IGN ProLeague Season 3 Championship - Winners Round 1, Game 2 (Shattered Temple) (IGN YouTube VOD). Unique in that it used not one but two Vortexes to deal with Stephano's attempted army split.
