Reveal season for The Witchwood – the next Hearthstone decks with only odd cost cards and decks with only even cost cards , not to mention new mechanics like Echo and Rush. And a whole lot of random Shaman spells.

“ Toki is a time traveller... and tinkers with bending time and alternate timelines.

Best case scenario.

Not quite as good.

Since this is the first set of the year, the introduction of The Witchwood also means a new Standard rotation, so we’ll be saying goodbye to Whispers of the Old Gods, One Night in Karazhan and Mean Streets of Gadgetzan. All those cards will still be playable in Wild, of course, but in Standard it means big changes - there'll be no more Jade and no more Old Gods, for instance. It’s going to be a whole new world, and the drastically reduced card pool means that the new cards will have a chance to really shine.Speaking of which, IGN has a new card to reveal – one of the two Mage legendaries in the set – Toki, Time-Tinker:As you can see, Toki is a 6 mana 5/5 with the battlecry “Add a random legendary minion from the past to your hand.” What does that mean? It means she’ll only pull legendaries that are exclusive to Wild – even if you’re playing in Wild. Those legendaries can be from any class too. Chromie and tinkers with bending time and alternate timelines. I'm not sure why she's a tinker as opposed to a tinkerer, but the idea is that she creates a portal to the past and calls for help from legendaries whose time in the sun has passed.It’s a very cool idea, but to be honest, this is not likely to be a card that sees much competitive play, as Toki’s base stats aren’t strong enough to justify the insane variance on what you could potentially get from her battlecry. Sure, if you high roll you might get Sylvanas Windrunner, Ragnaros the Firelord, Loatheb, Dr. Boom or Emperor Thaurissan, but even then you’ll still need to pay the mana to play the card.If you low roll, you might end up with Wilfred Fizzlebang, Rend Blackhand, Majordomo Executus, Nat, the Darkfisher, C’Thun, Finja, Madam Goya or Mayor Noggenfogger. (Not that the appearance of The Mayor could ever really be considered a low roll.)That said, if your whole strategy is grinding your opponent out, and your deck is full of cards that generate value, I think that on balance the card you get will likely be playable. The meta would have to be super slow to allow that, however, and it’s questionable whether you’d ever want this kind of randomness in a deck like that. I guess that the sort of deck that would run something like Cabalist’s Tome (which won’t be in Standard after the rotation, but gives you three random Mage spells for five mana) might think about including this. The difference being, of course, that Cabalist’s Tome had the potential to save you from being killed (Ice Block, Frost Nova etc) or give you lethal via burn. Very few of the cards you can get with Toki really offer you those possibilities. We’ve also seen a similar card revealed for this set – the Rogue legendary: Face Collector, which, while pulling from the format you’re playing in, as opposed to only pulling from Wild, seems a little stronger, as the Echo keyword – and its low cost – means it can effectively give you two or three shots at a good random legendary minion. Toki requires you to bounce it or use a copy or Brann-like effect, and that’s not something you’re likely to do. On the other hand, Face Collector doesn’t really fit the usual Rogue tempo gameplan, whereas a more controlling Mage is much more able to take the tempo loss from Toki.I guess we’ll just have to wait and see, but at first blush Toki feels like a spicy meme creation machine first and foremost. She’ll go in decks that are hoping to high roll into something insane and broken... and that's its own kind of fun.Want to know what's up with The Witchwood?
