Radagast the Brown

The digging here comes with a diversity clause that reshapes how you build the deck around it: the creature you reveal cannot share a type with anything you already control. That constraint does not turn the trigger off on a homogenous board (an entering Elf still lets you dig for a Beast, a Bird, a Giant), but it does penalize redundancy, because the deeper your board leans on one type, the more of your library becomes ineligible to grab. The result is a green value engine that quietly rewards a menagerie rather than a tribal pile, which is an unusual thing to ask of a color that has spent decades building typal payoffs. The dig depth scales with each creature's own mana value, so your cheap bodies peek and your fatties plunge; the card wants a curve that widens as it climbs. Because the look happens on any nontoken creature entering rather than only on cast, it plays cleanly with blink, reanimation, and flicker effects that drop bodies onto the battlefield outside the normal cast step. The whiff is the tax on ignoring all this: no legal reveal buries the top X cards on the bottom, so a deck stuffed with overlapping types leaks its own advantage back into the library. The 2/5 frame does defensive work, letting a four-mana engine hold a stalled board while the triggers accumulate around it.
