I mean he's gotta be aware that Super Silver does
exist in Pre Genesis canon right? Even if Death Battle were to play fair and allowed Trunks the Dragon Balls, it wouldn't do anything since the form of immortality granted by the DBs doesn't prevent other means of death and the whole summoning thing won't do shit since Silver would be much stronger then any Time Patroller summoned.
Also it's weird that he mentions the individuals who call Ian Flynn unreliable but doesn't elaborate
WHY people are saying that, I wonder why?
