How does the repeat mechanic work with counterspell effects? Are they two separate spells that must be countered separately, or does a single counterspell counter both?

Ruling: A single counterspell will counter both the original spell and the repeat effect, as they are treated as the same spell.

Nuances:

• If a repeat spell has the original spell not target an enemy unit/gear, but the repeat effect does target an enemy unit/gear, cards like Not So Fast can likely be cast on it to counter (because the spell will have a matching unit as a target overall), but this needs confirmation from the new rules.
