As a tech choice i'd recommend swapping out
Zurzoth, Chaos Rider for the black enchantment
tainted Remedy. Zurzoth does make bodies but they have no type, and he makes you discard randomly which means you might accidentally throw away combo pieces in your hand. If you want efficiency in your plays and consistency in your execution you want to avoid the confusion and randomness (unless the chaos IS the theme of the deck). By adding
tainted remedy you keep opponents from gaining life and any life-linkers they may have will actually hurt them too. With your
angel of destiny and this enchantment then you can mow down people's life totals. This also helps you because you're focusing on combat so the last thing you want is them gaining life on you since you have to swing every turn to keep them in check. Also if life gain is a win condition for you then you might also want to add
true conviction. This way your knights hit a bit harder on the battlefield AND you get some life link as well. What are your thoughts on this?
