When can you play units directly onto a battlefield? Can you conquer and play units on the same battlefield in the same turn?

Ruling: You need to have a unit on a battlefield to play units directly onto it (control it). You can move a unit onto an open battlefield and then play another unit from your hand onto that same battlefield in the same turn.

Sequence:

• Move or place a unit onto the battlefield to establish control
• Then play additional units from hand onto that battlefield

Nuances:

• Some card effects may allow placing units on open battlefields without needing control
• If you sacrifice your only unit at a battlefield as a cost (like with Cruel Patron), you lose control before the new unit is played, so you cannot play it there unless you control another unit at that battlefield
