After using Gust to move an attacking unit during combat, does the opponent have priority to play spells before combat ends and damage heals?

Ruling: Yes, after Gust resolves there is still a window for either player to play action or reaction spells before combat ends. The opponent can play Hextech Ray on the Deadbloom before it heals.

Sequence:

• Moving the Ravenbloom starts a showdown
• After Gust resolves, a new round of priority begins
• Both players must pass priority without playing any cards for the showdown to finish
• Only after the showdown finishes does combat end and damage heal

Nuances:

• Every time a card is played, a new round of priority starts after that card resolves
