Crystal pvp was created on accident, but it would be cool if Mojang leaned into it heavily, and started adding more combat usable explosive blocks/ entities with their own sort of strengths/ weaknesses, particular mechanics, kind of like how end crystals can only be placed on obsidian/bedrock and deal lots of damage on everything above said obsidian/bedrock, beds can be obtained cheaply early game but only usable in nether/end and unstackable, then there's respawn anchors but you need lots of crying obby and glowstone and need to be good at hotkeying to be fast with them.
There should be an extension of this category of weapons like maybe crystals that are crafted with wither skulls instead of ender eyes and deal wither effect in addition to the explosion damage, and are placed on soul sand/soil, and turns explodable blocks into soul sand/soil instead of destroying them. Maybe there should be an item/tool that turns normal obsidian into crying obsidian, kind of like how you can add wax to a copper block to preserve it, as a means of countering being hit-crystalled, but make this item renewable but hard to do so, like xp bottles. Maybe a flint and steel enchant that makes TNT detonate faster. Also curse of gravity like in this mod,
https://www.planetminecraft.com/mod/moai-s-mo-curses/ but make it incompatible with netherite armor, so you have to choose between KB resistance/durability buff and fast falling. There could also be a type of crystal that is much more powerful, with a guaranteed totem pop with being hit crystalled, but is really expensive, ie can only be placed on netherite blocks. Also, buff fishing rod durability and make cobwebs renewable to make alt crystal pvp metas more viable. Another thing that might be cool would be a non stackable item that allows you to swap places with the closest player/mob to counter hole camping. There could also be a block/entity that can only be exploded by being squished by a falling anvil, as well.
