Draft is a thing.
Also Blitz lets you keep your creatures, this just kills them because poison triggers on attack; adrenaline is worse than no adrenaline when poison is involved imo, although for cards with 3- attack it doesn't really matter. Faster, maybe, but not better over a length of time. DR is also great against adrenaline, whereas not as much against hard hitters which means that pretty much any shield hits this card hard. As I said, outside of OTK or last-turn damage burst this wouldn't see much use. Blitz can be used in damseltal for instance, where you pretty much can blitz the opponent to death.
