One of the many exciting new features that will be introduced in Warlords of Draenor is the Toybox. The toybox will include items which have some sort of novelty effect, and will function in much the same way as your pet journal. The idea is to free up bag space by putting the items' spells into a book which you'll be able to access across all of your characters.
I think we know where this is going and what it will likely mean to loot collectors… Although no formal announcement has been made about whether or not WoW TCG loot items will be included in the Toybox, I think it's pretty safe to say that they will. Blizzard has announced that the Toybox will contain things with fun item effects, which has got to mean that all of the novelty WoW TCG loot items will be in there.
Update: All of the loot items on this page will be accessible via the Toy Box tab – with the exception of the Epic Purple Shirt and Tabard of Flame.
Provided this is the case, in Warlords there's a darn good chance you'll be able to use things like: Dark Portal Hearthstone, Flag of Ownership, Foam Sword Rack, Grim Campfire, Magical Ogre Idol, Statue Generator, Throwing Starfish, etc…across all of your characters! How awesome would that be..?!
If the Carved Ogre Idol makes it into the Toybox, which it should, you can bet that will make a few players happy.
With the additions of the pet journal, mount spellbook, and the upcoming Toybox, I think it's safe to assume that a tabard manager of some sort will also be headed to WoW in the not-so-distant-future. It seems to make sense considering their desire to eliminate things that are taking up valuable inventory space, while also making them account-wide so that all of your characters can use them. That would also be a very welcomed addition to the game.
I'll keep you updated as more news is leaked about the upcoming Toybox feature. Let's hope that the TCG items will be included!
