🔍 What Actually Determines Rotation?
Rotation is based on regulation marks, not set names.
- Leaving Standard: All G Regulation cards
- Staying Legal: H, I, J, and future marks
This means: 👉 A card from 2023 might still be legal if it has a newer reprint with an H/J mark. 👉 Older prints of cards like Rare Candy or Boss’s Orders rotate, but newer reprints stay legal.
