In t2 this doesn't seem to be as much of an issue for a variety of reasons,
But in t1 I'm really feeling like generally speaking offense is 2:1 to defense for nearly everything. Cards printed containing 4 or 5 cards like Moses, Auto, CoL, Throne etc
We simply do not see defenses with these kinds of capabilities in t1.
I get that the point of the game is to rescue and not block, but it is also why I get the feeling these days sometimes you are better off not blocking at all rather than blocking only to give your opponent +6 or more cards and an opportunity to sabotage your own offense.
