If Deadbloom is played targeting an occupied battlefield, and the opponent responds with Gust to empty it before Deadbloom resolves, does Deadbloom still enter the battlefield?

Ruling: This scenario cannot happen. Units do not linger on the chain like spells do - they enter the chain but leave immediately as part of the play process, before opponents can respond.

Sequence:

• Steps 1-5 of playing a unit (including entering the chain) happen all at once before the unit becomes a real item on the chain
• The unit immediately enters the battlefield
• Only after the unit has entered the battlefield can opponents react

Nuances:

• Spells linger on the chain and can be responded to, but units do not
• You cannot react to units being played (including Shen from the chain or Teemo from hidden)
• You can only react after units have already hit the battlefield
• If a unit is put into play by a spell effect (like Dazzling Aurora), you must respond to the spell before it starts resolving - once resolution begins, you cannot interrupt it
