This should be an occasion I guess? My first post, though this is going to be about minecraft. I was working on summoning an armor stand that had a shield with a banner on it in 1.9. I am sure people have a solution for this, but I figure this could be a fun first topic.

/summon ArmorStand ~ ~ ~ {Invulnerable:1b,ShowArms:1b,Rotation:[90f],ArmorItems:[{id:"diamond_boots",Count:1b},{id:"diamond_leggings",Count:1b},{id:"diamond_chestplate",Count:1b},{id:"diamond_helmet",Count:1b}],HandItems:[{id:"diamond_sword",Count:1b},{id:"shield",Count:1b,tag:{BlockEntityTag:{Base:12,Patterns:[{Pattern:cbo,Color:0},{Pattern:flo,Color:9}]}}}],DisabledSlots:2039583}
