Yavimaya, Cradle of Growth makes every land a Forest, which means Llanowar Druid's tap-and-sacrifice ability untaps all lands you control — enough to pay Kenrith's fifth ability at and reloop. Each iteration generates a net positive in green mana because the untap refunds more than it costs, and Kenrith's haste grant or reanimation ability fires as many times as the loop runs. The table sees a Kenrith shell — likely 5-color goodstuff — assemble three permanents and immediately threaten every win condition on the card at once.

Variations

Cheaper, tighter, alternate lines

Yavimaya is the hardest piece to replace since it's doing the Forest-typing work; without it, Llanowar Druid's untap requires actual Forests, which constrains the mana base significantly. If Llanowar Druid is removed before the loop closes, Quirion Ranger or Wirewood Symbiote can substitute as the untap engine in Forest-heavy builds. The combo generates infinite mana but still needs a sink — Kenrith's own draw ability at closes the game by decking opponents, so no additional kill card is required.
