I guess if we are wishlisting though, hobgoblins would be neat.
Oooh! I agree!
Magic the Gathering is a separate IP. This would be like having Wookies from Star Wars in the game.
MtG and DnD are closer IPs than one might think. Both games being owned by the same company, MtG has had more than one set designed around the DnD IP (including one set designed specifically around BG3). DnD has had more than one book based around worlds created for MtG, including Ravnica whence hail the Simic. The infamous Silvery Barbs cantrip, for example, came from a DnD book based on Strixhaven, an MtG set.
None of this is to say I expect any MtG crossover in BG3. In fact, given we have an MtG set designed around BG3, I'd say any creature type not in that set is very unlikely to appear in BG3. Looking to that card set, here are the creature types we have yet to encounter in BG3, though they may not be playable races (mild spoilers):
- Dragon Barbarian (dragonborn)
- Fish Horror (Aboleth, whatever that is)
- Pheonix
- Sea Hag
- Artificer (as a player class)
- Bird Wizard (called Aven in MtG but could be equivalent to Aasimar in DnD)
- God
- Elephant
- Angel
- Hippogriff
- Dragon Horror (yikes!)
- Orc
- Elk
- Zombie Wizard (Lich)
- Horror Pirate (whuut?)
- Squid Horror (I'm not sure what's up with all the Horrors)
- Fox
- Cat Beast (Displacer Kitten)
- Mole
- Kithkin Wizard (I'm willing to bet Kithkin won't be in BG3; they're a variant of halflings, basically)
- Elemental Shaman (Genasi)
- Gith Monk (specifically, that card is called Githzerai Monk)
- Jellyfish
- Aetherborn (race specific to MtG, not sure how it would translate to DnD)
- Merfolk
- Naga
- Kraken
- Cat Warrior/Cat Rogue (they don't look like Tabaxi to me, but what do I know?)
- Hydra
- Azra Warrior (no clue what Azra are)
- Fearie
- Leviathan Horror (yeesh...)
- Phyrexian (MtG's equivalent of the Borg from Star Trek; I'm 99% sure there will be no Phyrexians in BG3)
- Thopter (little flying machines. would be a cool addition!)
- Whale (I'd be suprised if BG3 had that many sea creatures, if any at all)
- Human Boar (I don't want to know)
- Elemental Spirit (Chwinga?)
- Dragon Turtle
- Insect Bat (Stirge)
- Kobold
- Dragon Peasant (you do you, dragon. no more noble purpose than working the land)
- Scorpion (described as Tlincalli? Is that a thing?)
- Crab Ooze Horror (lol)
- Lizard Warrior (Lizardfolk, probably?)
- Bird Demon (Vrock... apparently?)
Oh I forgot they already had something from the MtG Settings in the game.
And some of those creature types on your list like Azra were simply reprints for the Commander Decks, so they don't count (In CL sets Commander Decks are concidered apart of the main set, just not draftable, and don't get a seperate expansion symbol).
I'll also add that there was that free adventure with AFR that had the Ravnican villian in the Forgotten Realms. Despite coming from Magic the Gathering, the Campaign Books GMGtR, MOoT, and S:CoC are all written as if they occur in the main cosmology, Theros for example is mention as being in the Material Plane and Strixhaven has Tieflings, Halflings, Slaads, and Dragonborn for example.
Also the Naiad from MOoT appeared in Candlekeep Mysteries with new art.
