Wyll's Reversal is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Choose target spell or ability with one or more targets. Roll a d20 and add the greatest power among creatures you control. 1—14 | You may choose new targets for that spell or ability. 15+ | You may choose new targets for that spell or ability. Then copy it. You may choose new targets for the copy.
Complete guide
Wyll's Reversal is a versatile red instant that allows you to hijack the plans of your opponents by redirecting their spells. By combining the unpredictability of a d20 roll with the strength of your board state, you can even gain a copy of the spell for yourself. It is a powerful tool for any commander deck looking to turn an opponent's advantage into their own victory.
What It Does
This spell targets any spell or ability on the stack that has at least one target. Once it resolves, you roll a d20 and add a bonus equal to the greatest power among creatures you currently control. Depending on the total, you always get to choose new targets for the original spell, but a high roll of 15 or more also grants you a copy of that spell or ability under your control.
How It Resolves
First, you choose a legal target spell or ability with targets and pay the mana cost. Upon resolution, you check the power of your creatures to determine your roll modifier and roll your d20. If you roll 1–14, you simply change the targets of the original spell. If you roll 15+, you change the targets of the original, then place a copy of that spell on the stack. You can choose new targets for your copy as well. Note that your copy resolves first because it is placed on the stack above the original.
Common Mistakes
A frequent error is assuming you can change the modes of a spell, such as choosing a different option on a modal card; however, the copy must use the same modes as the original. Additionally, while you control the copy, you do not control the original spell—you only change its targets. Finally, remember that creating a copy of a permanent spell (like an Aura) results in a token, but this does not count as 'creating' a token for cards that trigger on token creation.
When to Play It
Wyll's Reversal is best saved for high-impact targeted removal or game-ending spells. Because the bonus is based on your greatest creature's power, it is most effective in decks with large threats, ensuring you hit that 15+ threshold to copy the spell. It acts as both a defensive redirection and an offensive duplication tool.
Interaction examples
If an opponent casts Chaos Warp targeting your best creature, you can cast Wyll's Reversal. If you roll a 10, you simply change the target of Chaos Warp to one of their permanents. If you roll a 16, not only do you change their target, but you also get your own Chaos Warp copy to target a second permanent they control.
While Deflecting Swat is often free if you control your commander, Wyll's Reversal offers higher upside. Unlike Deflecting Swat, which only redirects, Wyll's Reversal can generate a copy of the spell. If an opponent targets you with a massive burn spell, Wyll's Reversal could allow you to hit them with their own spell twice if you roll high enough.

How it works : Wyll's Reversal
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
Even though you do not gain control of the original spell or ability, you control the copy. That copy is created on the stack, so it isn't "cast." Abilities that trigger when a player casts a spell won't trigger. The copy will then resolve like a normal spell or ability, after players get a chance to cast spells and activate abilities. The copy will resolve before the original spell or ability.

- #2· Wizards of the Coast
The copy will have the same targets as the spell or ability it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
No other card is named in this ruling.
- #3· Wizards of the Coast
If the target spell or ability is modal (that is, it has a bulleted list of choices), the copy will have the same mode(s). You can't choose different ones.

- #4· Wizards of the Coast
If the target spell or ability has an X whose value was determined as it was cast, activated, or put on the stack (like Fireball does), the copy has the same value of X.
No other card is named in this ruling.
- #5· Wizards of the Coast
You can't choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell or ability are copied as though those same costs were paid for the copy. For example, if you sacrifice a 3/3 creature to cast Fling and then copy it with Wyll's Reversal, the copy of Fling will also deal 3 damage to its target.
No other card is named in this ruling.
- #6· Wizards of the Coast
If the spell is a permanent spell with a target (such as an Aura spell), and you create a copy of it, the copy will become a token that you control. Because the spell becomes a token, the token isn't "created." Effects that care about a token being created won't interact with a token that enters the battlefield because Wyll's Reversal copied a permanent spell.
