Shaco, the Demon Jester

When Shaco, the Demon Jester enters the battlefield, each opponent discards a card.
Shaco, the Demon Jester can't be blocked as
long as it's attacking alone.
When Shaco, the Demon Jester dies, create two
1/1 Toy Construct artifact creature tokens with
"When this creature blocks a creature, that
creature doesn't untap during its controller's
next untap step".
