The Tokenator
Whenever The Tokenator attacks, you get two token counters. Then create a creature token with the color(s) and creature type of your choice. Its power and toughness are any combination equal to the number of token counters you have. (For example, if you have four token counters, it can be a 0/4, 1/3, 2/2, 3/1, or, if you’re really sure, 4/0.)
