Dunno. Arcane Tricksters tend to have a higher DEX modifier than INT (and then pick spells that don't care about the spellcasting modifier), so they are better off with Booming Blade (if stealth is already off the table) or Green Flame Blade unless they run into something that is resistant or immune to nonmagical damage at levels 3-4 and don't have magic weapons. Might work well with a maxed INT Arcane Trickster / Bladesinger build though.
