Whenever a Forest you control enters, create a 5/3 green Elemental creature token.
Whenever an Elemental you control dies, you may mill three cards.
Titania turns landfall into an army by making a 5/3 Elemental every time a Forest enters, then recurs those Forests from the graveyard for repeatable value. You ramp into Titania around turn 5-6, then chain land drops, fetches, and mass-land effects to flood the board with beaters while milling yourself for more fuel. You win by going wide with fat Elementals and overwhelming the table with land-based recursion.
Generates huge token bodies off something you do anyway—playing lands.
Built-in graveyard recursion lets Forests come back over and over for value engines.
Mono-green gives access to the best ramp and the format's strongest land synergies.
Resilient to wraths since the engine refuels from the yard and continued land drops.
Many tokens are 5/3, dying to almost any chip damage or a single -3 effect.
Slow without enablers—just casting Titania alone does little immediately.
Mono-green struggles to interact with spells and combos.
Relies on extra land drops or fetch/Forest-bounce effects to truly snowball.
