The Weaver's Trap

At the beginning of your upkeep, secretly
choose a number between 1 and 5 that
hasn't been chosen. If you do, an opponent
guesses which number you chose, then
you reveal the number you chose. If they
guessed wrong, they lose life equal to the
number they guessed and you draw a
card. If they guessed right, sacrifice The
Weaver's Trap.
