If Facebreaker is cast targeting two units on the same battlefield, but one target is removed (e.g., by Gust) before Facebreaker resolves, does the remaining unit still get stunned?

Ruling: The correct ruling is uncertain and debated. The most supported interpretation is that if one target becomes invalid, both targets become illegal and no stun occurs, because "same battlefield" is a targeting restriction that cannot be verified when one target is null.

Nuances:

• The "do as much as you can" rule applies, but only if targets remain legal
• The ambiguity stems from whether "at the same battlefield" is a targeting restriction that must be continuously met or only checked during target selection
• Multiple experienced players changed their initial ruling after discussion, leaning toward "no stun" when one target is removed
• Dreaming Tree would still trigger when targets are selected, regardless of resolution outcome
