That´s easy, I will just put death astray in my deck so my opponent can complete the challenge :0. Or you can try to deal the 50 damage with self-destruct sieger and lose through lifelink lose when tempest is eventually destroyed. On the other hand, I am sure there are decks that should be able to easily avoid taking 50 damage for 7 turns so... You might need to make some decent rules if you are serious.
