Suicidal Thoughts

Imprint — , : You may exile an instant or sorcery card with mana value X from your hand. At the beginning of your upkeep, you may copy a card exiled with this artifact. If you do, you may cast the copy without paying its mana cost.

Creatures can't attack you unless their controller pays for each creature they control that's attacking you.

Look at the top five cards of your library. For each card, put that card into your graveyard unless you pay 2 life. Then put the rest into your hand.

If you control a creature, damage that would reduce your life total to less than 1 reduces it to 1 instead.

Destroy all creatures.

Flying : Target creature gains indestructible until end of turn.

At the beginning of your upkeep, if you have exactly 1 life, you win the game.
