Whenever Radagast the Brown or another nontoken creature you control enters, look at the top X cards of your library, where X is that creature’s mana value. You may reveal a creature card that doesn’t share a creature type with a creature you control from among those cards and put it into your hand. Put the rest on the bottom of your library in a random order.
If a token copy of Radagast the Brown enters the battlefield, its own ability will trigger.

If the top X cards of your library don't contain a creature card that doesn't share a creature type with a creature you control, you won't get to put a card into your hand. Apologies to Mistform Ultimus fans everywhere.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
