Niv-Mizzet was OK as the Firemind (for the era) and is somewhat better as a Dracogenius
If you can attach this red aura to a chump creature, then heck yes an additional combat is worth the cost
Also, once again, in 1v1 gameplay, you yourself will be one of the 2 players, meaning your equipment, controlled and owned by you, will fall off the creature because it can't be targeted or equipped by your stuff as soon as it has protection from you, making it quite the useless sword
Risen Reef: On its own merits, this card just looks like a worse, but still playable Coiling Oracle
Then transform Dowsing Device if you control four or more artifacts
