I'm not too sure why this topic is in merchant forums... seems more like a general topic?
There is almost always a better card choice for hodrem in every situation. Some regular maps like Nogg are a weird mix of races and sizes etc. but that's more of a unique case.
Also, platinum shield offers both the medium and large resist a hodremlin offers (along with undead race resist). And there aren't that many small monsters either so platinum shield is kind of fine for most situations you would use a hodremlin. Putting a hodremlin in a valk shield gives you elemental resists though.
I usually refer to hodremlin as more of the "lazy" card choice. It's OK for everything but usually not the best. But with all the weird TIs we get, it's almost like the GMs are trolling the players and maybe players really should just default hodrem every week...
Another "use" of hodremlin is for putting it in very expensive shields that you are mostly using for "general use". For example, a +12 immune shield for the extra neutral resist, or a Bible of Promise Vol. 2 (AB only though, and requires level 140+). It's too expensive to buy several of these for every race, and you might still want to use them in general PVM situations.
Although if you do have a +12 immune shield, and are stacking other neutral resists (namely Deviling Card), a hodrem starts to make more sense there and actually offers quite good reduction against pretty much ANYTHING (except elemental attacks).
But overall, everyone really should have a set of most of the common races' shields. They can even just be in round bucklers or whatever.
