Playing the duo

Sion's Roar of the Slayer(E) can knock a minion carrying Tristana's nearly stacked Explosive Charge(E) into a champion, carrying the bomb for a ranged detonation; Sion's E also reduces the target's armor.

A charged Decimating Smash(Q) or Unstoppable Onslaught(R) can hold enemies in Tristana's attack range while she adds stacks to Explosive Charge(E).

How to play as Sion

When the relay will not line up, start with Decimating Smash(Q) or Unstoppable Onslaught(R) and let Tristana stack her bomb on the controlled target.

How to play as Tristana

Coordinate the minion relay with Sion: add three bomb stacks, then have him use Roar of the Slayer(E) through the target. The timing is narrow, so skip it if the angle is not clean.
