Koma, Cosmos Serpent doesn’t destroy target token creatures you control.
===========================
Specifically, when I have Koma, Cosmos Serpent on the board and token creatures, in particular:
- Skeleton tokens from the support card named Skeletal Swarming
- Decayed Zombie tokens from the creature card named Tainted Adversary
===========================
According to the text of the card:
… At the beginning of the combat on your turn: You may destroy target creature you control. …
===========================
This particular trigger “beginning of the combat” doesn’t activate of both token types described above.
It is possible that this is a specific case with a particular type of token with the particular planeswalker but the issue there so it looks like it should be fixed.
===========================
Here is the deck for Ashiok, Nightmare Muse that can consistently replicate the bug.
