When conquering a battlefield that has a 'discard 1 and draw 1' effect, and my unit also has a 'draw one when conquering' effect, what order do these effects resolve?

Ruling: When multiple abilities trigger at the same time (such as "when you conquer" effects), the owner of those abilities chooses the order they are placed onto the Chain.

Sequence:

• Both the battlefield's conquer effect and the unit's conquer effect trigger simultaneously
• The player who controls both abilities chooses which order to place them onto the Chain
• The effects then resolve in the order chosen
