Can I play Deathbloom Predator to an opponent's battlefield and simultaneously play a friendly unit with Ganking to attack together?

Ruling: No, you cannot move multiple units simultaneously when playing them from hand. You can only move one unit at a time when playing cards.

Nuances:

• This same restriction applies when using Set's signature spell - you cannot move other units with it
• Multiple units can only be moved at the same time through standard movement, which is the inherent capacity of moving units by exhausting them
• Any movement that involves playing a unit from hand is restricted to moving only that single unit
