Search your library for a basic land card or Town card, put it onto the battlefield tapped, then shuffle. When you search your library this way, put a +1/+1 counter on target creature you control.
原文You don't choose a target for Prishe's Wanderings at the time you cast it. Rather, a second "reflexive" ability triggers when you search your library this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
