Ondu Spiritdancer + Secret Arcade // Dusty Parlor

Overview

If you cast Secret Arcade // Dusty Parlor (either half) as an enchantment spell, Ondu Spiritdancer’s "Whenever an enchantment you control enters" ability will trigger when that enchantment enters the battlefield and you may create one token copy of it (only once each turn). If Secret Arcade’s front half is already on the battlefield, it makes your nonland permanents and permanent spells enchantments in addition to their other types, so casting a permanent spell counts as casting an enchantment spell for triggered abilities that watch for casting an enchantment spell , and permanents that enter will be enchantments on the battlefield . Token copies created by Ondu enter as copies and will have any enters-the-battlefield effects trigger as appropriate, but Rooms that enter the battlefield without being cast enter with both halves locked per Ruling [2024-09-20] and token copies enter that way too; copied enchantments’ ETB abilities still trigger per Ruling [2023-07-28].

Step 1

You cast one half of Secret Arcade // Dusty Parlor from hand. The cast half is an enchantment spell while it’s on the stack (both halves are enchantments by card type). The cast is a 'cast an enchantment spell' event for abilities that are watching for casting an enchantment spell .

Step 2

If Dusty Parlor (back half) itself is on the battlefield before you cast something else, its triggered ability 'Whenever you cast an enchantment spell...' will see you cast any enchantment spell (including permanent spells that are enchantments due to Secret Arcade’s front half) because that ability functions while Dusty Parlor is on the battlefield .

Step 3

When an enchantment spell you cast resolves, it becomes an enchantment permanent on the battlefield at resolution . At the moment it enters the battlefield, Ondu Spiritdancer’s triggered ability ('Whenever an enchantment you control enters') triggers for that entering enchantment.

Step 4

When Ondu’s triggered ability resolves you may create a token that is a copy of that enchantment. The token enters the battlefield as a copy of the enchantment.

Step 5

Because the token did not come into existence by being cast from the stack, a Room token enters with both halves locked per Ruling [2024-09-20].

Step 6

Any enters-the-battlefield triggered abilities printed on the copied enchantment trigger when the token enters, and abilities written as 'as this enters' or 'enters with' behave as the ruling describes [2023-07-28].

Step 7

Ondu’s ability is limited to 'Do this only once each turn,' so even if multiple enchantments enter in the same turn, Ondu will only create at most one token copy that turn.

Resolution

When an enchantment you control (a Room or the other half of the Room card) enters the battlefield after being cast, Ondu Spiritdancer’s triggered ability triggers and you may create a token that's a copy of that enchantment (subject to Ondu’s "Do this only once each turn" limitation) . If Secret Arcade (the front half) is already on the battlefield, permanent spells you cast are enchantment spells in addition to their other types while on the stack, so that casting will count as casting an enchantment spell for abilities that say "Whenever you cast an enchantment spell" . Token copies created by Ondu enter as copies and will cause any enters-the-battlefield abilities of the copied enchantment to trigger normally, but Rooms that enter the battlefield without being cast (including token copies) enter with both halves locked per Ruling [2024-09-20] and the Room’s "cast"-watching abilities won’t trigger from the token entering (they trigger only when you cast spells) [2023-07-28].
