I was making a redstone creation (Capture the Flag using banners) and I needed to add a scoreboard objective for breaking a banner. However, I cannot create that objective because 'stat.mineBlock.minecraft.banner' is not an option. I made sure, and the beginning part, 'stat.mineBlock.minecraft.' is correct as things such as 'stat.mineBlock.minecraft.fence' works.
Try standing_banner or wall_banner.
