The most useless block ingame huh? Well, there are a lot of useless blocks. Like Sponge, or maybe the Dragon egg. But... each of these have a certain use. A use for decoration on adventure maps, or a trophy to say you beat the game.

(NOTE: This is the most useless block for MINECRAFT SURVIVAL. Not overall. If it were overall, it'd be podzol...)

Now... Podzol could be a contender for most useless block. It looks like chocolate pudding on top of crushed oreos with sprinkles of gummy worms on the top. It's basically like fancy dirt. The biome it comes in is not a waste, I just think the block is.

OKAY, THE MOST USELESS BLOCK IN MINECRAFT SURVIVAL IS... None! XD jkjkjk. It's bedrock. (Troll face here) I mean seriously, you can't do anything with it, it's useless. Thanks for coming!
