Step 1: Make sure you've stocked up on 3 of coins from xur. Step 2: Wait until mid match for a Sunbreaker to use his super. Step 3: Open the menu and Pop the 3 of coins (don't worry about how much time this step takes as sunbreaker supers last a minute each). Step 4: Challenge the ultra and in the slight chance you actually defeat this incredibly powerful creature an exotic engram may drop for you. *Suggested light level to attempt this activity is 330.
