I find anti health regen items awkward to build. Especially when you play a tank this round, a mage next round, then a physical hero another round. The items does not have any from of connection despite having the same passive in some way, making situations where the passive can be useful but the stats makes the item gold inefficient(Magic), or situations where the passive is not useful but the item gives enough stats to compensate for it(Physical) not realised on first sight. Instead, make some Component items that are ~500-1300 gold and have no stats other than their passive, and allow us to buy that.
