Scourge Demagogue

Plague 5 (This permanent enters play with 5 -1/-1 counters, and "Until the end of the turn this enters
play, you may exile a creature card from your
graveyard with a converted mana cost of 5 or more to
move 5 of each counter to 5 creatures.")
When a 1/1 creature enters play, each player puts
the top card of their library into their graveyard.
Remove a -1/-1 counter: Create a black 1/1 Pest
token that counts as an Insect.
