Her core abilities {{Ability|fetch}} cards with mana. She can fetch from her library or graveyard, giving mana to lands and non-lands fetched respectively. She can also fill her graveyard from her library, {{Ability|buff}} creatures, and perform gem conversion to green. Less than 10% of Land cards in the game cost more than 12 mana, so unless those are used, or the player has more than two lands in hand, the fourth level of One With Nature does not gain more mana, and may even gain less, than the preceding levels.
