Kaladesh block - specifically AEther Revolt - was amazing! I loved all the new mechanics and cycles, and the flavor of it all is fresh and unique. But, rather that me spouting on about how much I love the new cards, what did it do for Tokens?
First, I want to talk about Sram's Expertise. I think all of the cards in the Expertise cycle are awesome, but Sram's stuck out to me over Yahenni's. Another card that produces 3 tokens, AND it lets he hit most any card in my deck for FREE? Sweet value! 4 CMC is high on the curve though, and the tokens are not flyers. But the value on this card can't be ignored. I'm testing this card at one, in place of Secure the Wastes.
Next, the hype for Smuggler's Copter has finally reached me. Another high-value card that allows me to finally have some draw manipulation in the deck on a solid flying body for a good cost. Common stances against this card from other Tokens players include the obvious: it's not a token, and because of this, it won't last long in a game. These concerns are valid, as most removal spells the opponent has will be sitting in the hand; no one wants to blow a Path to Exile or an Abrupt Decay on one 1/1 Spirit when there's three more sitting on the field. As such, I will be testing at two, taking out Dismember and moving Anguished Unmaking to the sideboard. If any new card were to be taken out, Copter would likely be the first to go.
Finally, the biggest standout for me in AEther Revolt is Hidden Stockpile. It isn't a proactive card; it can only produce a token at the end of my turn. What I love about it, however, is its reactivity and utility. The activated ability allows me to constantly manipulate my topdecks, while giving me a token in return most of the time. Multiples on the field only make this better, and Revolt will also trigger off any fetchland I crack. It may not be as flashy as Copter or Expertise, but I love this card. I'm currently running two, but I may go up to three if it goes well.
