The problem is that the mind flayers control is so much weaker versus the otys since it provides no damage control except for against FQ and FGs that use growth, and quintessence makes the necessity of loboing creatures with creature control skills unnecessary.
The point of 3 otys would be to draw one earlier; you wouldn't play more than 1.
ffq: ok, oty is better but flayer faster and stalls a lot, also very often good for animated ees
dark matter: can help against early nymph and won games (still not many)
eldinig: oty better again but fast out it helps against spirits, ultis, etc
eternal phoenix: you could use for phoenix and then firestorm
dream catcher: again, oty better but flayer good against early be
gemini: often helps against monumentum, oty better
graviton: its real strenght, otys, firemasters, etc. you can steal shield(ea if possible) and dont have to play a firestorm => better than oty early
hermes: fast at the start, not better than oty but nice
osiris: nice cause very fast, nice addition with otys
scorpio: also very fast, so nice.
FQ: You usually don't need to lobo animated EEs; you have quintessence.
Dark Matter: Oty is better for an early nymph, since you can steal a gravity tower.
Elidnis: Quintessence makes other uliths unnecessary. Mind flayer DOES have some help with spirits, but I'd rather eat them versus lobo them. And if they're so big that you can't eat them, you don't want that damage just hanging out on the field so rewinding or mutating + eating is strictly better.
Phoenix: Spams phoenixes too fast for one little mind flayer doing some loboing to really matter. An oty doesn't really make a difference either, but...
Dream Catcher: As you said, oty is better.
Gemini: You don't need to lobo if you can mutate + eat. Or steal the electrocutor. Really if you get to the point where it's necessary to lobo momentum, you're probably going to lose anyway.
Graviton: Sure, it can help with the fire masters and loboing momentum. So can eating them after firestorm is bettah.
Hermes: Fast Oty > Fast Mind Flayer any day. Especially with quint.
Osiris: Just deck him out anyway. Though it may be possible to not have to take so long with a mind flayer.
Scorpio: Again, fast oty > fast mind flayer. And with permafrost, you can take care of those puffer fishes (the only real threat, lobo-wise) easily.
Oh, and you're also using aether for quint and water for permafrost, so it's not like it's using unused elements.
