You're right. I used
chalice of the void in this list just for testing on my Cockatrice, sometimes is pretty good (on second turn I can counter everything is converted mana cost 1) sometimes is bad (like you said, it can stops my spells, so I have to cast as the last spell). I think
paradise mantle is a great add, because we need mana in this deck to
accelerate the combo. I love this deck! I'm talking it in real life
Thanks again!
