Others

 * Sven's kit is quite versatile and generally speaking there are very few heroes that Sven doesn't make a good ally with.
 * In general, any hero with lengthy stuns or roots will synergize well with Sven.
 * Because of Warcry, Sven makes a particularly powerful ally in teams with heroes with little armor, especially if they have otherwise large sums of HP, as his whole team can become extremely resilient to physical damage, which is a very powerful advantage of late game scenarios. Example of heroes with little armor but with other forms to survive fights include, , (Note: Though the hero starts out with strong armor, this will be quickly outweighed by his abysmal agility growth) and.
 * With enough mana regeneration, it's possible for Sven to be run as a roamer and help land kills with Storm Hammer. Though this limits Sven's early farm significantly, it is possible to catch up in farm and transition into full core with neutral creep stacks and Great Cleave. Consider this strategy if your team has an overabundance of cores, as most heroes are incapable of catching up in farm as easily as Sven can, so denying your other cores of farm could be significantly more detrimental to your team than denying Sven's farm.
 * Sven Works good vs armor Reduction strategies consider maxing warcry early if the enemy is going for armor reduction heroes of items like Desolator or Solar Crest
