Small details like this make a massive difference when it comes to Pokemon, as we've seen with the most expensive Burning Shadows cards
Getting to dodge a turn of damage and effects and then draw an absurd number of cards for the rest of the game is a complete package that probably shouldnt have cost four generic mana
Only about half the Lucavi Demons are ever fought, the rest never make an appearance
They are great when you have interactions that require you do do two things at once, say discard and Shallow Grave in response to the reshuffle trigger
It's not the same as taking on the actual human head-to-head, but it's still a boost to your ego if you can manage to take down the #1 ranked player's deck with your own, more meager stack of cards
Brawl players, in particular, should be very pleased by some nerfs being implemented at long last
