About the various things ...
Fragmentize: I just got annihilated by a mill deck that landed Sphinx's Tutelage on turn 3. Maybe I'll start running some too.
Take Inventory / Oath of Jace: After trying it out a bit more I tend to agree with you that the sorcery speed is too big a drawback. Take Inventory at sorcery speed is OK, but 3 mana for Oath of Jace is pricey. There are many times for example where I want to cast it on turn 4 but can't do so safely.
Planeswalkers: I don't understand how you can NOT tap out. For example another game I had recently had the other guy go Elvish Visionary on T2 and T3, and then Recruiter on T4. Clearly I have to Languish right? But that lets him play Nissa on T5 uncontested.
Removal spells: I forgot how I counted 7 removal spells, but that wasn't actually what I meant to say either! What is troubling is that you have so many removal spells that you will have a lot of dead cards against decks not running many creatures (like the Sphinx's Tutelage deck earlier).
Gisela: I find this card has both strengths and drawbacks. Main strengths are that she has three big keywords, and she only costs four mana. All three keywords are important. I find I often drop low on health early (like the Elvish Visionary turns I described earlier - adding an Anguished Unmaking on top of the beats would easily take me below 10), and Gisela's lifelink is a strong way to recover. First strike is also important; as long as Gisela stays in play for example the Scrapyard Scrounger that's causing you grief will not be a problem. Finally only costing 4 mana means she's one of the quickest win conditions to hit play while still leaving up counterspell backup. The drawback with Gisela is that she turns on opponent removal, and she's liable to die immediately to a card that costs less than 4 mana, losing even more tempo. Finally she requires Bruna, who otherwise is not very good. Without Gisela I don't think Bruna would be playable.
Gideon: What I dislike about this card is that it effectively only has one mode. I have attacked big Nissa before after chumping the 5/5 land, but that's the only time. Usually if I'm attacking with Gideon I've typically already won, and of course the emblem is close to useless in a deck with so few creatures. Still kind of have to run him though, since there are no replacements in his slow. If
Narset Transcendent were in Duels I'd probably run that instead too.
Glimmer of Genius: This card is obviously strong and would see play even without the energy, but what makes me itchy is that I have energy with no way to use it. I would be tempted for example to splash red for
Harnessed Lightning, something like that. After all, the deck already has Aether Hub and Evolving Wilds.
Evolving Wilds: Speaking of this card I tried putting it in and didn't see much of a difference. There ought to be
some difference, but I didn't detect it. Even without it I am seldom colour screwed. I would expect the deck-thinning to have some effect, but I didn't detect much difference either in how often I'm mana flooded. Very weird. The only thing Evolving Wilds has done for me is get Awoken by Planar Outburst, and then sacrifice itself to trigger Avacyn.
Anyway as I mentioned it feels like Esper is less powerful right now compared to before KLD, when the deck won as much as 90% of the time. Do you not feel that way? I want to get really good at a deck, but I'd also rather play a tier-1 deck (also playing Esper tends to feature me spamming on the "stop timer" button only to have it not respond a bit too often).
EDIT: Think I'll just steal your deck ... nothing I'm making seems to be working ...
EDIT #2:
So very first game I run into a burn deck with Dynavolt Tower. He spends the first few turns doing nothing and I do nothing as well. Then on turn 4, he throws Collected Defiance at me and makes me discard my hand. I decline to counter since I have no lands. On turn 5, he does the same thing, and again I decline to counter since I had lots of creature removals that would do nothing against his deck. However this lands both Gideon and big Jace in the graveyard. After this exchange he tries Gearhulk on T6, which I counter of course. His hand is now all burn, which he doesn't do anything with since I have no creatures.
At the end of one of his turns, I attempt Archangel Avacyn, which resolves. The next turn he attempts to Twin Bolt Avacyn, and I exile his Dynavolt Tower with Anguished Unmaking in response. He throws Galvanic Bombardment at Avacyn, and I decide to counter. The angel stays in play, hits him for four and I tap out to play flip Jace, since I had no more counters in hand + only had two lands untapped anyway. Then he burns the angel out on his turn and plays Hanweir Garrison. The Garrison gets to attack once before I draw Sorin and the -3 kills the Garrison. Jace flips and he concedes.
Thing is, he didn't have to concede. He could deck me out. I had drawn fourteen cards via Collected Defiance, and three of my win conditions were in the graveyard. With Sorin at 3 loyalty, even if he doesn't have the burn to kill Sorin, it would be a very long time before I can ultimate him, and all that time the +1 would be burning through my deck even faster. If even one burn spell connects with Sorin I'd be in even more trouble. The only other win condition in the deck is Torrential Gearhulk, but that can also be burned out, or at worst chumped with stuff like Hanweir Garrison tokens, and that's assuming I draw the Gearhulk early enough for it to be able to attack enough times to win. I certainly didn't feel like I was winning, in fact that I was losing. But that shouldn't be. I had answered all his threats, I ought to be winning instead of losing.
Either I'm terrible at post-KLD Esper or the deck is something I don't understand.
