I cast Channel then cast Triplicate Titan paying 3 manas and 6 life. My opponent cast Mystic Confluence with modes : draw a card, counter target spell unless you pay 3, counter target spell unless you pay 3. I pay 3 using chaannel for the first mode. I sacrifice a scion token and pay 2 life to pay for the second mode. Then my Triplicate Titan is still countered, and I lose the game two turns later.
