[confirmed]Spiny Starfish no regen self, checks wrong time

[Korath]

Describe the bug:

1. Spiny Starfish can't regenerate itself. fixed
2. If something else like Niall Silvain or Draconian Cylix regenerates it, Spiny Starfish creates a delayed trigger at the moment it's regenerated, and only if at that time it's a Spiny Starfish that hasn't lost its abilities.
   Expected (and observed) behavior:
   1. I have a Spiny Starfish, it regenerates, then I attach a Lignify to it: it shouldn't create a token at end of turn. (It does.)
   2. I have a Spiny Starfish, I cast a Lignify on it, then it regenerates, then I Disenchant the Lignify before end of turn: it should create a token at end of turn. (It doesn't.)
   3. I have a Spiny Starfish, it regenerates, then I cast an Infinite Reflection on a Drudge Skeletons: the Skeleton that used to be a Starfish shouldn't create a token at end of turn. (It does.)
   4. I have a Drudge Skeletons, it regenerates, then I cast an Infinite Reflection on a Spiny Starfish: the Starfish that used to be a Skeleton should create a token at end of turn. (It doesn't.)
   5. I have a Spiny Starfish, it regenerates, then I cast a Humble on it: it shouldn't create a token at end of turn. (It does.)
   6. I have a Spiny Starfish, I cast a Humble on it, then it regenerates: it shouldn't create a token at end of turn. (It doesn't, but for the wrong reason.)
   7. I have a Spiny Starfish, it regenerates, then I exile or bounce or successfully destroy it: it shouldn't create a token at end of turn. (It does.)
   8. I have a Spiny Starfish, it regenerates, then I Donate it: it should create a token for my opponent at end of turn. (It creates one for me.)

Which card behaved improperly?
Spiny Starfish.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
df88666 from 2017 Dec 14.

What exactly should be the correct behavior/interaction?

1. : Regenerate Spiny Starfish.
2. Spiny Starfish has a normal nondelayed beginning-of-end-step trigger that creates tokens if it regenerated that turn. It doesn't matter if, at the time it regenerated, it was a Spiny Starfish or whether it had its abilities. It does need to be a Spiny Starfish, still on the battlefield, and have its abilities at the start of the end step. ("Until end of turn" timing, whether on loses-all-abilities effects or becomes-a-copy effects, should still be active at that time. They mostly aren't.)

Are any other cards possibly affected by this bug?

1. Extruder looks suspicious. (No, it doesn't look anything like Spiny Starfish, but it uses the wrong enum type the same way the Starfish does.)
2. No, there's no other card with an ability that requires looking back in time to see whether something regenerated.

Fixed only can't regenerate in commit 89324a1.
