Rulings
One official ruling, as Wizards published it.
- 2026-03-20
If the first mode of Borrowed Knowledge was chosen but the target is illegal when Borrowed Knowledge tries to resolve, it won't resolve and none of its effects will happen. You won't discard your hand or draw any cards.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
