Slardar, Lion, Rhasta, Alchemist, Windrunner

Nuf said.

Lion, Rhasta are okay, but alche is a single stuner same with windrunned. I'd say Es, or mag , or tide would out stun those heros by far.

Tide = whole view screen stun for 4 seconds
Es = Massive damage while holding stun for over 5 seconds,
Mag = drags all in and stuns for 5 seconds

Best combo would be

Magnataur starts the gank (Imagine 5v5) and blinks in and uses Reverse Polarity to drag everyone in for the stun of 5 seconds .
Then ES blinks in with his ulti, doing crazy damage since everyone is close and theres prolly more than 5 units cuz of creeps.
Then Tide will just own them with his ulti after es's stun runs out for 3-4 seconds which would prolly kill all the dpsers like clinkz or such leaving around 1 or 2 depending on which hero.
If this is excuted perfectly they should still be in their circle with less than 30% of their hp left for whoever is alive. Then Lion would stun all 5 on them with a 2.5 second stun.
During all this Rhasta sets up his Wards ( 10 ) x 2 (If you got refresher ) where each ward does like 40 chaos damage. 20 x 40 = 800 Chaos damage PER SECOND for over 15 seconds of stun.
The wards do cleave damage so if they were all set together, no matter how tanked they are, they should all die.

Actually a little better would be one who doesnt stun but works just as good

Lion/Rhasta/Dark seer/magnus/es


Dark seer runs in with his uber speed, vaccums then at that time magnus blinks in and ults. then es comes in big stun to block + Ult Lion stuns / ult the tank

Rhasta ward/lightning during all that

Seer sounds a lot better tbh

something like lina / sandking in one lane es / potm in another works well, in mid you can have roof or something its not too bad.. but i think mass stun isnt always the solution.. after 20~30 minutes people start to have disable items.. guinsoo is often far more useful than a stun (instant cast time) etc.
