How does this interact with Schrodinger's cat? Does it turn into a immaterial creature or generate one?
This card technically requires a creature to actually die, rather than just have an ability to trigger death effects, so Schrodinger's cat probably wouldn't be affected by this card.
Sorry, I do not see the logic here. Dying creatures and death effects are the same thing. The scrodinger cat actualy dies when its ability is triggered, excpet that it's paradoxically still alive due to quantum uncertaintiy. When a kitty ability is triggered, it should create another reborn kitty with 0 atk immaterial and ability.
A death effect is a part of a creature's death, but the removal of a creature does not have to result in a death effect being triggered (e.g. Reverse Time). It is technically possible to design a spell that triggers death effects without a creature or a creature that does not trigger a death effect when it dies.
Ataraxia requires a creature to copy when something dies. If just the 'death effect' part of a creature was triggered (e.g. A 1
spell that 'triggers all death effects'), it would not be able to to copy anything because no creature actually died for it to copy.
(The 'dying' kitten from Scrodinger's Cat is just a graphical effect, iirc, since no actual 'creature' with stats or abilities appears - just the 'death animation' of a dying Schrodinger's cat. The actual effect of the ability is technically "trigger all death effects.", so like the example
spell I mentioned above nothing will be created because coding-wise nothing actually died. Correct me if I'm wrong, but this is how I've always seen it work.)
This will actually be a very nasty (potentially OP) card. Consider:
Vulture,
Spark
Fractal
This
-> mass bumping vulture every round!
Alternately, put in boneyard and nightfall.
And note: You will NEVER stop the skellies attack since nightfall would passively bump them to +1 attack after being reborn. (consider interaction with burrowed devourers)
Creatures that revive from Apatheia or Ataraxia are given a passive called "Apatheia". Creatures with the Apatheia passive cannot be revived with Apatheia or Ataraxia.
^Because of the Apatheia passive you can't infinite loop Sparks even if you have both Apatheia and Ataraxia out. This is similar to how Graveyard doesn't create a skeleton if a skeleton dies.
That means you need a 5 card combo consisting of Vulture, Spark, Fractal, Boneyard, and Apatheia or Ataraxia in play to get sufficient damage. Fractal/Spark/Vulture should already be a viable OTK and any additional cards are likely overkill IMHO due to Fractal-Spark already dealing most of the damage. (most OTK's require at least 2 Cards + Fractal or Skyblitz to work with the rest of the deck built to get that combo into play.)
One questions: does no ability mean just active abilities or does it include passive ones as well? E.g. does it function like a lobotomizer, or something more heavy handed. If it leaves passives this will have an ugly synnergy with devourers (lobotomizing devourers only removes burrow, not the quanta drain).
Currently, all abilities (including passives) are removed unupped except for the Apatheia passive that is given. While upgraded does retain abilities it is probably more efficient to use quintessence on singular creatures. Fractal Devourers with Apatheia requires at least 3 cards to get the lock in place and you've probably already been locked if you allow the devourers to come out in sufficient numbers, IMHO.
