I'm guessing the addition Multiple Choice over something simple like Opt or Deliberate is because it's less of a dead flip with Kefnet? Mode 2 & 3 just seem so underwhelming.

Has Cavalier of Gales overperformed in your experience? It seems kind of expensive for a non-Instant/Sorcery value card. I also feel like cutting Wasteland , your only land hate as far as I can tell, is risky. I'm guessing you got Hall of Oracles for commander damage support, so I'd suggesting undoing the Wasteland/Hall swap and instead cut the Cavalier in favor of Runechanter's Pike again

Resculpt is obviously a thing

Coward_Token - Opt is here! Best off-turn Kefnet trigger in the deck, haha - would never remove it.

Goal with Multiple Choice is to always hit mode 4 off Kefnet. Most likely play after that is just to cycle it with the first mode. Worst case scenario, hit it on mode 4 again.

Cavalier of Gales has absolutely overperformed - here's the thing about about this deck: Brainstorm and Dream Cache are super important for setting up loops, but even then are obviously great as single cast to get the right stuff on the top of your library - or even dig for Kefnet if he dies. Cavalier can do that too, but as a second Brainstorm effect, he can put Brainstorm or Dream Cache back on top of the library (if I tutored for them or drew them while Kefnet was offline), setting up a new loop. I'd call him a "pet" card for me for this deck.

You're probably right about Wasteland . I don't think I can squeeze in another colorless, so I'll probably swap it back at some point. Just testing out some new stuff for now!

I might swap Deliberate for Telling Time honestly. Telling is one of my favorite cheap blue spells but it also doesn't have as much synergy with Kefnet because it doesn't draw cards.

My bad, I think I saw Opt but then forgot about it again while writing the comment ._.

Do you have a special angle with Multiple Choice 's bouncing in mind or do you just want flexible jack-of-all-trades, master of none value?

Coward_Token - Nothing fancy; but sometimes I can reuse a Snapcaster or Spellseeker or Mnemonic Wall if I name myself.

That's the idea at least. Haven't played it yet.
