Cobbled Deepslate crafting recipe

Using quartz and cobblestone, the player is able to craft the 1.8 stone varieties. This is the only way to obtain these blocks in challenge modes like superflat survival, or skyblock. Deepslate is a hassle to obtain in larger quantities, even in regular worlds, as it cannot be instantly mined with the best equipment. Blackstone and basalt don’t have many uses, and could be used in a crafting recipe with cobblestone to craft cobbled deepslate. This gives challenge players proper access to the family of deepslate blocks, and makes blackstone and/or basalt a desirable block, instead of an annoyance.
