Toad Rider

Horsemanship (This creature can't be blocked except by creatures with horsemanship.)
Rally - Whenever Toad Rider or another Ally enters the battlefield under your control, you
may look at the top four cards of your library. If you do, reveal any number of Squirrel Ally cards from among them, then put those cards onto the battlefield tapped and the rest on the bottom of your library in any order.
