Sincere Pumpkin Patch

When Sincere Pumpkin Patch enters the battlefield, search your library for a planeswalker card, reveal it, and put it into
your hand, then shuffle your library. If you revealed a card named The Great Pumpkin
this way, put it onto the battlefield instead.
At the beginning of your upkeep, create a 2/1 pumpkin creature with "this creature cannot
be blocked"
