Got in a few games today, and things definitely felt good. I suspect part of that may have been because I got to
Narset's Reversal two
Cathartic Reunions (in different games with different players), which felt fantastic. Still, I definitely felt the effects of lowering my curve and adding a few more mana rocks. My general heuristic is that this deck will win around the time it hits 8 mana, so a lot of my recent efforts have been to (1) slow down the game so I live longer and (2) improve my ability to hit land drops and ramp to that point faster. Once I get there, pretty much any big X / draw spell will be enough.
Anyway, I do have a few counterspells lying around that I'm planning to add in - I have spare copies of
Counterspell and
Negate, plus I picked up a copy of
Thassa's Intervention, which seems like a great fit. Not sure if I want to add
Mystic Confluence back, but I might.
One other thing I noticed is that I want a few more flashback spells - I'm planning to add back
Deep Analysis, and throw in
Arcane Infusion. In the early game, I want to be able to generate a bit of card advantage and sculpt my hand, but that means I can run out of stuff to trigger Mizzix. Having a bit of additional value out of my graveyard should help, and the fact that they make good options to discard to any looting effects also helps.
Not sure how things are yet on the board wipe front - I've picked up a few more that I'm planning to test out (
Immolating Gyre,
Spectral Deluge, etc), but not sure how many I want total. Still, they are a good way to slow down the game - dying to random aggression is definitely one of this deck's primary concerns, due to its lack of blockers.
