Goku, Soul Awakener

Backup 1 (When this creature enters the battlefield, put a +l/+1 counter on target creature.
If that's another creature, it gains the following ability until end of turn.)

Whenever this creature attacks, double the
number of +1/+1 counters on target creature. That creature can't be blocked by creatures with
power 2 or less this turn.

“This is the power of a Super Saiyan.”
