If Hidden Blade is played against me and I react with Defy, do I still draw 2 cards?
Ruling: No, you do not draw 2 cards. When a spell is countered, it is removed from the chain without any resolution and none of the countered card's instructions will be carried out.
Sequence:
- Defy resolves
- The countered spell (Hidden Blade) is immediately removed from the chain
- Hidden Blade never resolves, so its draw effect does not happen
Nuances:
- The countered card does not count as a "played" card since it never resolved
- Once removed from the chain, the countered spell cannot be targeted by other effects (it no longer exists)
