Uh Yeah I'm That Guy vs Synaptic Interruption

Tachyon has Synaptic Interruption in play. Guise has Uh Yeah I'm That Guy in play and high-fived Tachyon. Blade Battalion deals Guise 5 melee damage. Guise uses Uh Yeah I'm That Guy (which has Synaptic Interruption's text) to redirect the damage to Baron Blade. After the redirection, should I destroy Uh Yeah I'm That Guy or Tachyon's Synaptic Interruption?

You would destroy Uh, Yeah, I'm That Guy as any destroy text on Uh, Yeah, I'm That Guy would refer to Uh, Yeah, I'm That Guy if the conditions are triggered of a copied Ongoing.
