Russian Roulette

You may reveal this card from your sideboard
before the game begins. If you do, create X
copies of Russian Roulette, rounded up, where X
is equal to the number of cards in your library
divided by 5, then shuffle them into your library,
then your starting hand size is increased by 1.
Dead Card (This card cannot be cast, discarded
or used to pay a cost or activate an ability)
In some games it is better to go second.
