Yup. Unless you invest a minimum amount of effort into finding someone who will trade you stuff. Go to the ZC page, enter 100 in the box, then click "Get Shareable link". Now post on the Trade Forums saying you want 100 ZCs for the Pikachu event, and tell people what you're willing to offer for it. Once you get a trade you will accept, send them the Shareable link from earlier and OMG you now have Zophan Canisters! Easy! Now go get a Pikachu ;)
