Damage prevention effects (erebos titan, enshrouding mist) are STILL preventing instant death effects (unholy hunger, turn to frog) from working properly.
Why not just hotfix such effects to do -500/-500 instead of doing damage to achieve their stated effects?
I get the impression that’s how they intend it to work, just like how hexproof prevents Displacement Wave and things like that. It’s not how the MTG paper rules work, but it’s at least internally consistent.
If that’s the case, they really need change the wording or call it indestructible or something, because too many people are used to the way the card game works…
