Zalgen, Malicious Alchemist

Prowess
{u}{b}{r}{t}: Sacrifice a creature. Each opponent discards a card at random. For each instant, sorcery, or enchantment discarded this way, draw
a card, then discard a card at random.
{2}: Roll a die. If the result is even, target creature gets +3/+0 until end of turn. If it is odd, sacrifice a non-token creature you control.
