All effective health scales well with Alistar's ult, if you will heal heavily than resists scale slightly better than usual.
Sword of the Divine is not a very niche item, most IE users can get good use out of it.
1. Eleisa's Miracle - outclassed hard by Ring now. No one really wants it. Viktor could try I guess, but he has far better things to get.
2. Guardian Angel is less useless on hypercarries who can do stuff while reviving and heal while reviving, like Mordekaiser.
3. Berserker's Greaves is useful on some autoattackers who can maintain distance and don't need so much CDR such as Kog'Maw.
4. Runaan's Hurricane is useful in some lanes to maximise lifesteal off multiple targets, Graves or Sivir could pick it up against Yorick.
5. Zeke's Herald I get occasionally on Blitzcrank, it provides useful health, CDR and lifesteal and supports other AD users on my team.
