Others

 * In general, any hero with lengthy stuns or roots will synergize well with Sven.
 * Because of, 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 outweighted 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 . 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 . 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.
