Why it works
- Sion's R has long range. "Unstoppable Onslaught" sets him charging at increasing speed (range 7500) and knocks down and damages the enemies he rams.
- Senna's R is global. "Dawning Shadow" fires a beam of enormous range that shields allies and damages enemies.
- Senna's W roots. If it hits, the enemy and those nearby are rooted shortly after.
- Sion's Q knocks into the air. Charged, it knocks up and stuns those it hits.
- Sion doesn't die easily. His passive revives him after death for a time.
Weak points: the charge's path is visible; each one is in a different lane at the start. To verify
