Kephilex, Chaos Incarnate

Partner with Thanaera, Order Incarnate.
Eminence- If Kephilex, the Living Chaos is in the command zone or on the battlefield, each player
may flip a coin at the beginning of their upkeep,
if it comes up heads they draw a card, then repeat
this process. If the player is an opponent, they
lose life equal to the number of cards drawn this
turn.
Whenever a player casts a spell from their hand,
it gains Cascade.
