Suggestions for the upcoming Winter themed drop

Overall I liked what I saw at Minecraft Live and am looking forward to its implementation. Here are some additional ideas I would love to see there.

- Ore Redistribution! I am glad you mentioned the ore problem specifically during the Minecraft Live because it is a rather serious one. It is unnecessarily annoying mining in any cave that isn't a dripstone or regular one because the majority of available ore spots are removed. It is self-defeating to visit most of these caves when you are losing out on so many resources. Please go back and add new ore types that correspond to each of the affected cave biomes. Mossy ore for Lush Caves, Sculk ore for Deep Dark Caves, and Icy ore for the new Ice Caves.

-Aquamarine Geode! Considering the crystally theme of this new biome, it would be criminal not to introduce a new exclusive geode with blue crystal blocks and matching growths. It would fit the aesthetic perfectly, besides, we need more blue blocks anyway. Speaking of which...

-Blue block family. Yeah add something like snowy bricks or compacted snow blocks or something. Blue blocks forever!

-Iceologer. Does any more need to be said? Low hanging fruit or not, this is the perfect opportunity to bring this mob back. 

Thank you
