April Fools - block of totem of undying

With nine totems, you can create the block of totem of undying. It can stack up to 64. It functions as a totem, but nine times stronger. It can also be placed, and as a block, it saves from death any entity directly above it. This is to mock how common the item has become with raids, and raid farms. Crafting one of them gives the advancement "Every Hardcore Youtuber's Dream." Of course, you can also craft bricks with it (and chiseled bricks, polished bricks, bricks with moss, pillars, slabs, walls, doors, etc).
