Robust with a few tricks up the sleeve. Nothing infinite, but ruthless nonetheless.
Between Lord of the Unreal and Grand Architect, the creatures you'll actually want to swing in with can get pretty big, and Lord giving them hexproof is almost too much to ask for. Anything worth swinging with has evasion in the form of flying, so there's another bonus. All tricks aside, the creature base can do some serious work by itself.
Now for the tricks;
If you cast Phantasmal Image over your own Lord of the Unreal, the copy will include itself in the static ability, giving itself hexproof and +1/+1, because it becomes an illusion in addition to its other types. Most lords are potent if not taken care of. This set up ensures a lord that can withstand anything short of a boardwipe.
Arcane Adaptation is there to take advantage of Lord of the Unreal and Krovikan Mist's power and toughness.
Grand Architect not only is a Lord for blue creatures, but also lets you tap your blue creatures for two colorless to spend on artifacts or artifact abilities. This works perfectly for casting or activating Isochron Scepter, especially when we don't necessarily want to swing or block with EVERY creature we have in play. Losing a Lord of the Unreal to combat is a bad feeling. Using it to cast an Isochron Scepter while it's still protecting everything is a good feeling.
Isochron Scepter only needs to have Banishing Knack attached to it. Again, with a Grand Architect out, all you'd have to do is tap two creatures to return a nonland permanent to their hand each turn. Otherwise, two mana and tapping a creature that isn't going to attack to return a nonland permanent every turn isn't such a bad deal either. Truly feel like the Scepter letting you recur it every turn is worth paying the extra one mana it normally costs. It's a welcomed tax for that amount of long-game control.
Elite Arcanist and Triton Tactics go together in a wonderful way. For one mana, you can untap the Elite Arcanist-that Triton Tacticts is on, and untap another creature as well. If only we had another creature with a tap ability... oh right! Banishing Knack gives any creature a really nice tap ability for the turn. So if we can seal an Elite Arcanist with a Triton Tactics, and get Banishing Knack to resolve on any other creature we have, we can set up a combo that goes; Pay one, (Or pay two if Banishing Knack is on Isochron Scepter, or tap one creature if Grand Architect is in play and Banishing Knack is on Isochron Scepter) Cast and resolve Banishing Knack on anything besides the Elite Arcanist. Pay another one. Copy Triton Tactics on the Elite Arcanist. In response, tap the creature that has Banishing Knack's ability. Now Triton Tactics resolves, letting you untap Elite Arcanst and creature X. You can now pay one more mana, to repeat the process. Once this is in play, every one mana you spend lets you return a nonland permanent they control to their hand, giving you a level of control that any blue player can respect; "Tap an untapped Island: Return Target nonland Permanent your opponent controls to its owner's hand."
Between the lords, evasion, and hexproof, mixed in with a splash of control that can be capitalized on in most situations, it feels like a very hearty and resilient deck with some unexpected and unorthodox interactions.
I wanted to stay in the scope of what could be considered an Illusion deck, and not use any kind of infinite combos.
Comments and suggestions are welcome.
