Create four 1/1 white Bird creature tokens with flying. Basic landcycling {2} ({2}, Discard this card: Search your library for a basic land card, reveal it, put it into your hand, then shuffle.)

Niche token generator for flying-focused strategies, but the five-mana cost and narrow payoff make it difficult to justify over more efficient creature producers or card draw in most Commander decks. The landcycling mode adds flexibility, though it's rarely the effect you want to be using in the late game when you're casting this.
