Practice the line offline: lay out the cards, walk through each step, and note where you can lose the combo (summoning sickness, lack of priority, removal on a key permanent). In game, announce each step clearly; in casual play you can offer to shortcut after demonstrating the loop.
The best window is a turn when opponents are tapped out or after they commit a spell — hold protection (a counter, Vexing Shusher) if the combo wins on the spot.
