Overview

You may use Zaffai and the Tempests to cast Peer into the Abyss without paying its mana cost (this is a cast; see ). Gandalf the Grey will trigger from that cast (triggers created after the spell is cast; see ). When Gandalf’s triggered ability is put on the stack you choose a mode (you must choose the mode as the triggered ability goes on the stack; see ). If you choose Gandalf’s copy mode, that triggered ability will target the Peer on the stack (targets must be legal when you choose the mode; see ). When the triggered ability resolves it will put a copy of the targeted Peer into the stack; a copy of a spell is put onto the stack and isn’t cast (it’s a spell on the stack under the copy controller’s control) as described in . The copy resolves separately from the original, and each resolution applies Peer into the Abyss’s instructions using the game state at that copy’s resolution (see ) and rounding up each time . Because a copy isn’t cast, Zaffai’s ability doesn’t interact with the copy (it only permits you to cast a spell from your hand once per turn).

Step 1

You use Zaffai’s once-per-turn permission to cast Peer into the Abyss from your hand without paying its mana cost; this is a cast and follows the casting steps in .

Step 2

After the spell has been cast and the cast is complete, Gandalf the Grey’s triggered ability triggers because you cast an instant or sorcery; that triggered ability is put on the stack as described by .

Step 3

As Gandalf’s triggered ability is put on the stack you choose one of its modes; you must choose the mode when the triggered ability goes on the stack and you can choose a mode that requires targets only if there are legal targets at that time ().

Step 4

If you chose Gandalf’s copy mode and targeted the Peer on the stack, when the triggered ability resolves it puts a copy of that targeted Peer into the stack under your control rather than casting it, per . You may choose new targets for the copy if the mode allows it (Gandalf’s text does).

Step 5

The copy and the original Peer are separate spells on the stack and resolve independently. Each resolution uses the game state at its own resolution to determine how many cards are drawn and how much life is lost () and you round up the amounts for each resolution ().

Step 6

If a resolution causes a player to attempt to draw from an empty library, that draw attempt is allowed (see ) but can cause that player to lose the game by state-based actions ().

Resolution

Sequence and results: You may cast Peer into the Abyss from your hand without paying its mana cost due to Zaffai (this is a cast; see ). Gandalf’s triggered ability is put on the stack and you choose its mode as it’s put on the stack . If you choose the copy mode and target the Peer on the stack, when that triggered ability resolves it creates a copy of Peer and puts that copy onto the stack (). The copy is not cast (it’s a copy on the stack) so Zaffai’s once-per-turn permission does not apply to that copy (). The copy and the original resolve separately; each resolution uses the game state at the time it resolves to determine how many cards are drawn and how much life is lost, and you round up for each resolution (; ). If a resolution attempts to draw from an empty library, that attempt is allowed but may cause that player to lose the game by state-based actions (; ).
