Crucible of Worlds + Glacial Chasm + Oracle of Mul Daya

Overview

You can play Glacial Chasm from your graveyard thanks to Crucible of Worlds or from the top of your library thanks to Oracle of Mul Daya, but playing it is still a land play (a special action that must be done on your turn during a main phase with the stack empty) . Oracle of Mul Daya increases the number of lands you may play that turn (so you can play more than one land) (Ruling [2009-10-01]). When Glacial Chasm enters the battlefield its triggered “sacrifice a land” ability goes on the stack and will force you to sacrifice a land you control when it resolves; if you control no other lands you must sacrifice Glacial Chasm itself (Ruling [2008-08-01]). Crucible allows you to play lands from your graveyard but does not let you activate abilities of land cards while they are in the graveyard (Ruling [2018-07-13]).

Step 1

Make sure it is your main phase, you have priority, and the stack is empty so you may take the special action to play a land .

Step 2

Decide which zone you will play Glacial Chasm from. Crucible of Worlds lets you play lands from your graveyard, and Oracle of Mul Daya lets you play the top card of your library if it is a land; both are permissions to 'play' the land rather than 'put' it (Ruling [2018-07-13]).

Step 3

Check how many lands you may play this turn. Oracle of Mul Daya grants an additional land play each turn, increasing your allowed number of land plays for that turn (Ruling [2009-10-01]).

Step 4

Play Glacial Chasm as a land (special action). Because playing a land doesn't use the stack, it enters the battlefield immediately and then you receive priority .

Step 5

When Glacial Chasm enters the battlefield its triggered ability “When this land enters, sacrifice a land” triggers and is placed on the stack. You may respond to that triggered ability, but you may not play another land while the stack is nonempty because playing a land requires the stack to be empty .

Step 6

When the triggered ability resolves, sacrifice a land you control. If you control no other lands at that moment, you must sacrifice Glacial Chasm itself (Ruling [2008-08-01]).

Step 7

After the trigger resolves and the stack is empty, you may take further special actions including playing additional lands up to the limit provided by Oracle and other effects .

Resolution

You may play Glacial Chasm from your graveyard using Crucible of Worlds (Crucible grants permission to play lands from your graveyard) or from the top of your library if it’s the top card and Oracle of Mul Daya allows it; both are land plays and count toward the number of lands you may play that turn (Oracle’s extra land play increases that limit) (Ruling [2009-10-01]). When Glacial Chasm enters the battlefield its enter-the-battlefield triggered ability triggers; when that trigger resolves you must sacrifice a land you control, and if you control no other lands you must sacrifice Glacial Chasm itself (Ruling [2008-08-01]). You cannot play another land while Glacial Chasm’s triggered ability is on the stack because playing a land is a special action that requires the stack to be empty .
