Krampus, Santa's Substitute

Haste
When Krampus enters the battlefield, tap target creature you control. That creature doesn't untap
for as long as you control Krampus. Krampus gets +0+X, where X is that creatures toughness.
Whenever Krampus attacks, you and defending
player each create a Present token. (A Present
token is an artifact token with "Sacrifice this artifact:
You gain 1 life.")
