Ervin, Chaos Singer

When a player would draw a card instead they
shuffle their library. Reveal the bottom card
of their library, put that card into their hand.
{b/r}{b/r}: All players shuffle their libraries, then
exile the top card of their libraries. Each player
then flips a coin. If they lose the coinflip exile
the top card of their libraries.
"Revel in the embers of uncertainty."
