Euron's Plan to Trick Victarion & Claim a Dragon - Winds of Winter Predictions - Song of Ice & Fire

How does the dragonbinder really work? We know "all Euron's gifts are poisoned," so it's obviously some sort of trick and trap to ensnare Victarion, but how is that going to work? How does giving Vic the dragonbinder and sending him to Meereen lead to Euron claiming a dragon? Which dragon, and where? I have answers to all of these questions with a new Winds of Winter Predictions theory! It's a trap, Victarion, don't blow that thing!
