: Add Dryad of the Ilysian Grove gives lands decks both an additional land play each turn and broad color fixing. While it is on the battlefield, your lands have every basic land type in addition to their existing types. Those types grant the normal mana abilities, allowing a utility land to supply whichever color your next spell requires.
The extra land play works well with Life from the Loam or Crucible of Worlds, which help keep lands available in hand or the graveyard. Aesi, Tyrant of Gyre Strait and Tatyova, Benthic Druid reward the additional entries with cards. Dryad does not find lands itself, so those sources of continuing material help it contribute after the opening hand is depleted.
Valakut, the Molten Pinnacle gains a notable interaction. Dryad makes your lands Mountains, allowing them to help satisfy Valakut’s requirement and allowing entering lands to trigger it when at least five other Mountains are present. Scapeshift can build toward that plan, but the exact result depends on the lands entering and Dryad remaining available for the relevant type checks.
Dryad does not make lands basic, remove their existing abilities, or let you play lands on an opponent’s turn. It also does not grant additional land plays once it leaves the battlefield. Because it is both a creature and an enchantment, several kinds of removal can answer it. Use it when the deck wants the extra land development and can turn the type-changing effect into more than incidental fixing.
