Accelerating DECK-struction II: The Rise of Sleepy [Sign-ups Closed]

i just wanted my card to go through... shield breaker. it got rejected for being able to instakill any creature. but how else is it supposed to "break shields"? have an effect that works only on Shield? obviously i'm thinking about this game like yugioh, where monsters have a short lifespan.

re: the keeping cards thing, i always figured this game was like ascension. i think its the same as dominion, you are forced to play or discard all of your cards, in exchange for getting a fresh supply. the deck continuously recycles itself this way. makes sense, given our ability to add to it, like with ascension. and i would prefer it this way. not like keeping cards would break the game, but i like the challenge of having to string together your cards in the best possible way in one turn
