Strategy
This upgrade is arguably the most powerful in the game overall, but is not always easy to use. Tanks that can make good use of a Magnet have to be able to reliably kill enemy tanks faster than the enemy can kill them, but, because the Magnet itself takes up a slot, you are at a disadvantage to do just that. Tanks that can make the best use of a Magnet tend to be a blend of quick, tough and aggressive, or tanks that can attack from cover.
