Can I move units to a battlefield where I just lost a showdown?

Ruling: Yes, you can move units to a battlefield even after losing a showdown there. There is no restriction on how many times you can move units to the same battlefield.

Nuances:

• You can move units to the same battlefield one at a time if you choose
• You can even move the same units that just participated in the showdown if you can ready them and they didn't die
