The good news: THE POWER OH MY GOD THE POWERRRRRRRR
The bad news: Not so great on the 'support' front, entirely MP reliant

As the Black Mage job level increases, additional spells are added to this list, as well as increasing the power of the Magic stat transferred.

Does exactly what it says on the tin.  The only learned ability worth actually equipping in a Natural Job challenge.
Success Strategy
Abuse elemental weaknesses and deal huge damage.  Then get your next tier of spells just as the current ones are starting to feel weak and destroy stuff all over again.
But actually, the REAL secret of the Black Mage is rods.  If you haven't taken a look yet, go do so. Elemental Rods actually ENHANCE the power of certain element types by 50%!  You can also BREAK a Rod by using it from the item list in battle; this destroys the rod but instantly casts the spell - and boy do Black Mages have a high magic stat to take advantage of this!
Note that the first set of Rods (Fire/Ice/Thunder) are bought in Karnak, Act 1.  The Venom Rod is bought in Quelb, Act 2.  The legendary Wizard Rod enhances MANY elements at once.
Now go forth and DESTROY.
Spell List
Please remember that spells with a "chance" are affected by Magic Accuracy things - including boss Magic Evade which can make some of these spells a lot worse.  However, you never have to worry about the accuracy of spells without a listed rate.  See the Magic Accuracy mechanics section for information on how it works.
Note that all Black Magic can be reflected except the two exceptions that note it below.

Notes
Fire/Blizzard/Thunder

Act 1, various magic shops
Deals Fire/Ice/Bolt damage elements respectively
Equip a Fire/Ice/Bolt rod to enhance damage dealt
Poison
--
2
Act 1, Karnak/Crescent magic shops
99% chance of Poison
Poison works on several early bosses but is rare later
Sleep
--
3
Act 1, Karnak/Crescent magic shops
90% chance of Sleep
Target weak to Sleep & Poison?  Hehehehe...
Fira/Blizzara/Thundara
50
10
Act 1, Karnak/Crescent magic shops
That's 250% of the MP cost, for 333% of the damage of tier 1!
Toad
--
8
Act 1, Istory (Found)
Act 3, Mirage (If missed)
80% chance of Toad
Can be cast while Toad
Drain
45
13
Act 2, various magic shops
75% success rate. Recover HP equal to damage dealt
It might not be as strong as other spells, but it ignores Reflect!
Remember that undead enemies reverse the direction of Drains...
Break
--
15
Act 2, various magic shops
75% chance of Stone
On vulnerable enemies this is effectively an instant death spell
Bio
105
16
Act 2, various magic shops
Deals poison element damage, roughly 210% as strong as Fira/Blizzara/Thundara
Power it up further with a Venom Rod!
Causes sap, which steadily does extra damage.  NOTHING is immune to sap!
Bone Mail wearers will be healed by this(!), though be aware it'll still cause sap to them
Firaga/Blizzaga/Thundaga
185
25
Act 2, Moore magic shop
250% of the MP cost, 370% of the damage output of tier 2!
And let's not talk about the horrors with a matching element rod equipped...
Got no healer?  Use Firaga/Blizzaga on someone with a Flame Ring, Flame Shield, or Ice Shield!
Death
--
29
Act 3, Mirage magic shop
80% chance of instant death (Doesn't pierce immunity nor Heavy)
I believe fewer things are immune to instant death compared to petrification
Osmose
8
1
Act 3, Mirage magic shop
99% success rate, drains MP from enemies (Yes it can miss ): )
Though the magic power is low, it also factors in only a very small amount of the enemy's MDef, so it will still be effective on almost anything
Oh and of course you can't steal MP from enemies without MP
You can use Psych to drain MP from allies (especially noteworthy if the allies have no use for MP!)
And finally, remember that Undead foes reverse the direction of drain spells
Ignores Reflect
Flare
254
39
Act 3, Fork Tower quest
That's a freaking lot
Believe it or not it's actually WEAKER than Firaga/Blizzaga/Thundaga with a matching rod/on a weak target
Flare, however, ignores enemy magic defense entirely and can't be resisted!
It does NOT ignore Shell or Reflect though
Reflect Damage Multiplication
Only doable if your entire party is afflicted with Reflect (or at least safely).
Normally, multi-targeting a spell cuts its power by half.  If your entire party is under reflect, however, casting a multi-target spell on your own party will cause it to bounce four times, effectively doubling the final damage dealt by your spells! This also is a way to get around Reflect on enemies (such as Wall Knights), since spells can only bounce once.
