Here is a Aura spell and a legendary creature. I also have included some design notes. Please provide feedback focused on mechanical design and balance before flavor or lore.
IngenuityUU
Enchantment - Aura [R]
Enchant creature
Enchanted creature has "Whenever this creature deals combat damage to a player or planeswalker, you draw two cards." The basic instinct of a brilliant mind.
See spoiler below for Ingenuity design notes:
My intention here was to create an efficient reusable source for card advantage. The idea of creating an aura that doesn't suck is interesting to me. Keep in mind, auras tend to be one of the weakest card types because they are susceptible to two for ones and require a creature in play to be used. Sixth Sense, Curiosity and Keen Sense are similar cards that generally see no competitive play. Divination unconditionally draws you two cards at common for 2U. This card requires you to control a creature and deal combat damage with it to draw two cards and it is a rare. If you can successfully enable this card's triggered ability just one time, it is worth it's mana investment.
Vyana, Medium EnchantressWBG
Legendary Creature – Spirit [MR]
You may play enchantment cards from your graveyard with converted mana cost less than or equal to the number of enchantments you control.
Whenever you cast an enchantment spell from your graveyard, draw a card. 2/3
See spoiler below for Vyana, Medium Enchantress design notes:
I created Vyana, Medium Enchantress as a bottom up design. The primary intention was to design a legendary creature that has synergy enchantments and the graveyard. The triggered ability is an homage to enchantress cards. The color identity for Vyana, Medium Enchantress is WBG because white and green are the primary enchantment colors while black is the primary graveyard interaction color. The card may be acceptable to print without ruining most constructed formats (i.e. Legacy, Modern) but Vyana, Medium Enchantress was intended for the Commander format likely leading enchantress control decks (she also could fit well into the 99 of some decks).
I considered adding a once per turn clause on the first ability but considering you need to control multiple other enchantments to gain significant value in addition to paying the mana cost of the spell, I believe it is fine as is.
Ingenuity seems sweet, and is probably fine powerwise, certainly powerful.
Vyana seems absurd to me, due to several cards that break her, as Unbridled Growth or Seals (Seal of Doom). I'd say one per turn is a must. Then, it is still very powerful commander, but it doesn't do broken things with such ease.
I know when you say Medium you mean ghosts and stuff, but there's part of me expecting Small and Large enchantresses.
Ingenuity feels really swingy, particularly for limited. An unblockable creature with that aura is almost over the Divination curve, but in situations where the opponent can shut it off it's potentially a 2 for 1 in their favor.

I think Vyana, Medium Enchantress is strong but you are downplaying the significance of the converted mana cost restriction. To recur Seal of Doom, you would need Vyana, Medium Enchantress, three other enchantments, mana to recast the spell and you'd have to avoid graveyard hate. I do like the idea of making it once per turn and removing the CMC restriction, but that feels too much like its already been done before (Kess, Karador, Muldrotha).
Ingenuity, otoh, seems rather undercosted to me. I could see it being cmc 4, say. Draw two is very powerful.
If it had a CMC of 4, it would be terrible. When you compare Ingenuity to Sixth Sense the power level feels appropriate (Sixth Sense is an underwhelming card power wise that isn't a rare). Consider that Ingeunity can draw you two cards if you have a creature, and that creature deals combat damage to a player for UU. Divination draws two cards unconditionally for 2U. Auras tend to be very weak because as Hackworth mentioned, if you remove the enchanted creature, it's a 2 for 1. I do agree with Hackworth that in limited the card would be a bomb, but that's the case for a lot of rares.
Honestly, regarding Ingenuity, I strongly considered pushing it just a little more by having it also grant the enchanted creature Prowess.
