Pick these 5 heroes = 100% win

I'd say there are two types of teams who can easily win under proper conditions. First one is a team with balanced strategy potential: pushing, teamfighting, ganking, early-mid-late game, farming, etc. however isn't exceptionally good at any of them, playing the game nice and slow, balancing offence with defence and reaching the win steadily. Second one is the one that relies heavily on one of the aspects to end the game as fast as possible before they are countered, most of the time this team will initiate and play aggressively, hard to sustain against this team early game. Or they could play defensively trying to reach late game, so they re easy to shut down early. This team is more of the first one. Great tankiness and survivability overall in each one of them, good teamfight potential, fast XP and gold gain and really easy to pull off ganks, also good def/push potential. However this team can't cope with constant SPLIT pushing as individually they are a bag of durable meat. Split push early, disrupt their farm and they are useless late game.
