Can you use reaction speed spells to reduce the might of a unit targeted by Baited Hook, so that the opponent searches for a lower might unit?

Ruling: No, you cannot reduce the might to change what the opponent searches for. The unit's might is declared when Baited Hook's cost is paid and cannot be changed after that point.

Sequence:

• Baited Hook's cost is paid (unit is declared at this time)
• The might value is locked in and cannot be changed
• Baited Hook resolves and kills the unit
• Opponent looks at top 5 cards for a unit with the declared might value

Nuances:

• If you remove the targeted unit from the board at reaction speed, Baited Hook will still look at the top 5 cards and recycle them, but no unit will be played
