Dryad of the Ilysian Grove + Glacial Chasm + Ramunap Excavator

Overview
With Dryad of the Ilysian Grove and Ramunap Excavator on the battlefield, Glacial Chasm can be played and its “When this land enters, sacrifice a land” trigger will require you to sacrifice a land when that trigger resolves. You cannot play a land in response to that triggered ability because playing a land is a special action that requires the stack to be empty and . After the trigger resolves you may play a land from your graveyard using Ramunap Excavator (subject to your remaining land plays for the turn; Dryad grants an additional land play) and . Dryad also makes your lands have all basic land types (and therefore the associated basic land mana abilities) while it’s in effect (Ruling [2020-01-24]).

Step 5
After the trigger resolves and state-based actions are applied, you receive priority with an empty stack and may play a land from your graveyard using Ramunap Excavator, provided you have not exceeded the number of lands you may play this turn; Dryad of the Ilysian Grove grants you an additional land play each turn and .
Resolution
When Glacial Chasm enters the battlefield its triggered ability “When this land enters, sacrifice a land” is put on the stack. You cannot play a land in response to that trigger because playing a land is a special action that requires the stack be empty and . When the trigger resolves you must sacrifice a land. After state-based actions and the trigger resolution are complete, you get priority and may play a land from your graveyard with Ramunap Excavator (playing a land is a special action) if you have an available land play for the turn; Dryad of the Ilysian Grove gives you an extra land play each turn and . If you controlled no other lands when Glacial Chasm’s enters trigger resolves, you must sacrifice Glacial Chasm itself (Ruling [2008-08-01]). Note that Ramunap Excavator only lets you play lands from your graveyard; it does not let you activate land abilities from the graveyard (Ruling [2017-07-14]).
