my tourney winning combos, mainly cos synergizes well, and my team can play the heroes well:

1.
btm:
moprh+dark seer

top:
undying+leshrac

mid:
kk

morph+ds usually get fb, with ion+wave combo,if not enough. max ms and vacuum from ds really help
dirge and ts can usually get top twr down by lvl 6.
kk ulti can hit easy with vacuum, kk's ulti help ts tank abit to open ulti, dirge ulti amplifies aoe havoc.


2.
btm:
necrolic+wd+veno

top:
warlock

mid:
raijin

strat:
veno lvling up wards(to push twrs), pulling btm creeps
maledict+venomous gale will steer off gank attempts
necrolic benefits from poison+maledict for charges.

wl and ss roles are self explanatory.

This was inspired by EHome vs LGD.sGty match with slight improvements...hehe.

this is pushing strat la...
not every line up need tanker.
the 2 solos are strong enough, especially wl, with good stats gain.
raijin got good survivability with ulti.

I think you dont play competitive dota enough la...
where got ppl use AM with current metagame?

and lycan is not even a tank.

u can go to gosugamers to watch replays and dota commentary to learn more about competitive.
