Reverberate + Twincast

Overview

Reverberate and Twincast both copy instant or sorcery spells. A copy created by Reverberate is itself a spell on the stack and can be targeted by Twincast (or by another Reverberate). Copies copy the original spell’s characteristics and decisions, including chosen modes, targets, and any determined X value . You may choose new targets for copies when the copying effect allows it and choosing new targets follows the special rules for "choose new targets" . Rulings: Twincast can copy any instant or sorcery spell (including copies) [Ruling 2021-03-19]; if Reverberate copies a spell with an X whose value was determined as it was cast, the copy uses that same X value [Ruling 2010-08-15].

Step 1

You cast an instant/sorcery spell S; it is on the stack with its chosen modes, targets, and an X value if applicable .

Step 2

You cast Reverberate targeting S (you choose the target when you cast Reverberate) and it is placed on the stack above S .

Step 3

Players get priority and may respond while Reverberate is on the stack. If nothing responds, Reverberate resolves and puts a copy of S onto the stack under Reverberate’s controller .

Step 4

That copy is a spell on the stack. Because copies are spells on the stack, Twincast can target that copy when Twincast is cast, or Twincast can target the original S or even the Reverberate spell itself while it's on the stack [Ruling 2021-03-19].

Step 5

If Twincast resolves while targeting a spell on the stack, it puts a copy of that targeted spell onto the stack under Twincast’s controller. If Twincast copied a copy of S, the new copy copies the characteristics and decisions that were on that copy (which in practice are the same as the original’s choices unless targets were changed when that copy was created) .

Step 6

When copies are created and the copying effect says you may choose new targets (both Reverberate and Twincast contain this line), the controller of the copying effect may choose new targets for the copy, following the 'choose new targets' rule .

Resolution

A copy put on the stack by Reverberate is a legal target for Twincast, and Twincast can copy either the original spell, the copy created by Reverberate, or Reverberate itself (creating another Reverberate copy that will itself copy a spell when it resolves). Copies copy choices already made for the original spell, including targets and X values ; when making a copy you may choose new targets as allowed by the copying effect and those choices follow the "choose new targets" rule . See Ruling [2021-03-19] and Ruling [2010-08-15].
