For Garen's Legend ability, do you need to conquer with 4 units at the same time, or can you conquer with one unit and then play 3 more during the conquer point to trigger it?

Ruling: You must have 4 units on the battlefield when you conquer. After showdown, you need 4 surviving units on the battlefield to trigger Garen's ability.

Sequence:

• Showdown occurs
• Check if you have 4 units surviving on the battlefield
• If yes, Garen's ability triggers when you conquer
