When facing a BE deck this card can only negate syncros. Note that Spirit dragon effect to summon another syncro blue eyes doesn't count as syncro summon
In the ED, Steelswarm Roach is paired with Abyss Dweller. If the player sets, XYZ Abyss Dweller because that is a GY trigger. If the player sets TRAPS, XYZ Steelswarm Roach first because it wants to clear your board to summon a big stick.
