You should have somewhere on there to label it with the identity of the object those enchantments are attached to, including the object's name, controller and which copy it is if there's more than one in play under the same player's control.
I suspect that's why, at official tournaments, they don't let people put their mage enchants off to the side with equipment like nearly everybody does on OCTGN; they need this information to be absolutely perfectly clear to not just the players, but any spectators too.
I personally hope that the new modular arena has significantly larger zones. While the current arenas are quite large, they're simply not big enough for swarms, kill-zones solo or buddy builds.
