Both Bruna and Gisela are powerful cards on their own, one a beefy attacker, the other a top-end threat with a reanimate trigger on it
Should I sell Pokmon cards through an auction house
Ashe, Princess of Darkness A good limited creature for artifact heavy decks with an aggressive tilt, Ashes size is acceptable, just watch that she trades with any 2 powered creature
Those purchasing the precon Valgavoth deck will find more variability and opportunities for adjustment
Two mana 1/1s that make the opponent discard always play quite well, especially when a set has some sacrifice stuff going on
I see it as a requirement to play one because if you are attempting to win with Serra Angel and there is a Maze of Ith (commonly restricted) in play, you need more ways to destroy it than a single Chaos Orb (although Stasis is another solution to Maze after the first activation)
