The Struan

At the beginning of your upkeep, tap any number
of untapped creatures with total power 10 or greater
you control. If you do, The Struan becomes a
creature until end of turn. If you don't, sacrifice
The Struan and search your library for up to 3
Forest cards, put them into play tapped, then
shuffle.
The Struan can't be blocked except by four or more creatures.
