OK so this Eldrazi deck is the new hotness, and there's a lot of inexperience and/or sloppy players out there that are picking up this deck and smashing faces with it. I've noticed on Cockatrice that many of these players miss a trigger, and it's not the ETB one. "When TKS leaves the battlefield, target oppnenet draws a card." This is the trigger my opponents are missing, and in a comp REL tourney I'd love to call out players on this detrimental trigger they are missing, since it seems to fall on me to remember this every time it happens in a casual game.

What is the best way to call people out on this? When do I call the judge? Lets say it's my turn, I untap, I cast Swords to Plowshares on my opponent's TKS and it resolves. My opponent takes the card and puts in exile, and gains the life. He says nothing else. Presumably it's back on my main phase priority. What should I do there? If I remind him of the trigger I'm just helping him play his deck. The result I would like is for him to get a warning at the very least, for either angle shooting me with "oops forgot" triggers or more likely just sloppy play, that happens to benefit him. Should I just go for another action or pass priority on the phase, and then call the judge when he still says nothing? When the judge comes over and I tell him my opponent missed a trigger (of which I obviously haven't) will it look like I'm the one angle shooting?

Any input from experienced Comp REL players or judges would be greatly appreciated.
