The Limitless chip: one round with no budget
Limitless lifts the budget cap for a single round: you can field the most expensive assets available, and the lineup reverts to what it was for the next one.
A normal lineup lives under a $100M cap, and that cap is the main constraint in the game: you are nearly always giving up one strong asset to afford another. Limitless removes it for exactly one round.
The detail that matters is the revert. After the round the lineup rolls back to whatever it was before the chip, so Limitless does not help you rebuild long-term. It buys points on one weekend and changes nothing after it.
So it belongs on the round where the gap between expensive and cheap assets is widest: one where the favourites are near-certain to finish ahead and the midfield returns nothing.
The worst use is a round with a high chance of the leaders retiring. You are spending your only shot at a lineup of the strongest assets on a race where that lineup might not finish.
The comparison with Wildcard is simple: Limitless removes money, Wildcard removes transfer penalties. Limitless hands the lineup back, Wildcard lets you keep the new one.

Common questions
Does the lineup stay after Limitless?
No. After the round the lineup you had before the chip comes back.
Do the other lineup rules still apply?
Only the budget is lifted. Every other rule continues to apply.
