I did it with Yuyu + the UP buff.

If we only talk about the island i placed up Yuyu first on the leftmost part of it, then i can't remember if i placed up Cloris or my mincosted CC'd silver on the rightmost part but one of them. And with enough UP to spare i placed out some random un-CC'd silver in the top left to slow passing by wolves so Yuyu had enough time to get her skill up.
