Overview

When Mnemonic Deluge resolves you create three copies of an instant or sorcery card and you must cast those copies immediately during Deluge’s resolution . Casting those copies counts as casting spells for purposes of Howl of the Horde’s delayed ability, so the first copy you cast while Howl’s delayed ability exists will be the one Howl copies (and if Raid applied, Howl will make an additional copy) . The Howl-created copies are put onto the stack when the Howl trigger resolves, after Mnemonic Deluge finishes resolving; you may choose new targets for those copies .

Step 1

You previously cast Howl of the Horde this turn; it created a delayed ability that will watch for the next instant or sorcery you cast this turn (Howl’s ‘‘when you next cast...’’ delayed trigger).

Step 2

You cast and Mnemonic Deluge resolves. As part of its resolution you exile a target instant or sorcery card from a graveyard and Mnemonic Deluge creates three copies of that card and instructs you to cast those copies immediately without paying their mana costs .

Step 3

You choose the order in which to cast the Deluge-created copies and then cast them one at a time during Deluge’s resolution; each time you cast one it becomes a spell on the stack and any triggers that watch for 'when a spell is cast' are created at that moment .

Step 4

The first of those copies you cast is the 'next' instant or sorcery for Howl of the Horde, so casting it creates Howl’s delayed trigger. The second and third copies you cast do not trigger Howl because the delayed ability is used up by the first cast.

Step 5

Mnemonic Deluge’s resolution finishes. Now the game looks at triggered abilities that occurred during resolution and puts them on the stack. The Howl trigger(s) are put onto the stack now .

Step 6

A Howl trigger, when it resolves, will put a copy of the spell it refers to onto the stack (copies are put onto the stack and are not cast) . If Raid applied when Howl was cast, that Howl trigger will produce an additional copy when it resolves . You may choose new targets for Howl’s copies as allowed by Howl’s text .

Step 7

Those Howl-created copy spells resolve in due course (they were placed on the stack after Deluge resolved), then the original Deluge-created copies (the spells you cast during Deluge) will resolve/can be responded to in normal stack order.

Resolution

Resolve Mnemonic Deluge. During its resolution you create three copies of the exiled card and cast those copies immediately (you choose the order you cast them) . The very first of those copies that you cast this turn is the ‘‘next’’ spell for Howl of the Horde’s delayed ability, so casting it creates the Howl trigger. That trigger is created when you cast the copy but won’t be put on the stack until after Mnemonic Deluge finishes resolving; when the Howl trigger resolves it puts copy(ies) of that spell onto the stack (one copy, or two if Raid applied) and you may choose new targets for those copies . If you didn’t cast the copy (you declined to cast some of Deluge’s copies), the uncast copies cease to exist . If the original spell is no longer a legal object on the stack when Howl’s trigger resolves, Howl can’t copy it .
