D&D 5E A Knife in the Dark, A Rogues Handbook

Cantrips. You learn three cantrips: mage hand and two other cantrips of your choice from the wizard spell list. You learn another wizard cantrip of your choice at 10th level.

Greenflame blade is a wizard cantrip. It works great for Eldritch Knights too!

Do you happen to know what the source is for that cantrips? My Arcane Trickster will probably want that, haha.

Yeah, Sword Coast Adventurers Guide.

I still need to add an updated spell section to cover the new material. Hopefully that'll get done soon.

Would you consider rating Bladesinger 2 for a dip? I think it meshes really nicely on an AT, but it's still pretty good on other subclasses.

The weird thing about AT/Wizard multiclassing is that its value heavily depends on what level you multiclass at.

Your first wizard level gives +6 1st lvl spells known. Every other wizard level gives you +2 spells of your highest spell slot level. So, if an 18th lvl AT takes one wizard level (multiclass caster level = 7), that's six 1st level spells known & one 4th lvl slot... but no 4th lvl spells known. A second wizard level (character lvl 20) gives you two 4th lvl spells known & a second 4th lvl slot.

But let's say you reverse that and start your character with 2 wizard levels, taking 18 AT levels after. The AT has a different spells known progression, so you get your first 4th level slot as a multiclass character much earlier at character level 17, and you can also replace an AT spell known with a 4th level spell. By 20th level, you could have five 4th lvl spells known (4 through replacing AT spells, 1 learned at AT lvl 16/character lvl 18) and two 4th lvl spell slots.

I know you asked specifically about bladesingers, but multiclassing wizards of any stripe with Arcane Tricksters is complicated! More so than most combos, it really depends on what level you will be playing at and the order you multiclass in.

EDIT: I may be wrong about all of the above. See below for more info.

??? Your max spell level stays the same either way. Neither gets 4th level spells unless they would on their own.

Huh. The +6 spells of 1st level never really occurred to me as a problem before, haha.

Actually... a deeper split might be worth it. 6 levels for Extra Attack is probably pretty good, although you might be using the SCAG cantrips, and at that point you might as well go for Polymorph/Banishment/Evard's Black Tentacles (which imposes restrained, meaning free advantage against anything which fails its saves, which means free Sneak Attack), AND also all the spells and cantrips you couldn't get because of school restrictions or limited picks: Shield, Absorb Elements, Misty Step, Blink, Fly and, last but definitely not least, Haste, and of course more spell slots. You give up a decent chunk of Sneak Attack damage of course, and the usual class feature delay/loss is annoying, but it's definitely viable. In fact, you might even go for around an even split for more spells: 9/11, 10/10 and 11/9 jump to mind.

By 20th level, you could have five 4th lvl spells known (4 through replacing AT spells, 1 learned at AT lvl 16/character lvl 18) and two 4th lvl spell slots.

You still determine spells known for each class individually, "as if you were a single-classed member of that class." An AT needs 19 levels in the class to know 4th level spells.

Arcane Trickster: "Whenever you gain a level in this class, you can replace one of the wizard spells you know with another spell of your choice from the wizard spell list. The new spell must be of a level for which you have spell slots"

A Wizard 2/Arcane trickster 15 (multiclass lvl 7) has one 4th lvl spell slot. Can they not exchange one spell they know for a 4th lvl spell?
