couldn't you always play a deck with quint salvagers, eternities, dim shields, SoR, hourglasses, butterfly effect, photon and nightmare.
play photon and nightmare it. when the AI plays it you butterfly effect it and SoR it and quint it. Play quinted salvs on your side with one in hand to use with eternity to never run out of cards. use dim shields with hourglass, (they'll destroy hourglass first) to stop their damage for two turns and on it's last turn dont play the hourglass again. They'll still hit you, but only every three turns. If it turns out they'll target dim shields over sundials then you could stop their damage like that but you would eventually run out of the sundials.
Idk if that made sense, ... would it work?
