Doubling Season

Enchantment, 4G (5)
If an effect would put one or more tokens onto the battlefield under your control, it puts twice that many of those tokens onto the battlefield instead.

If an effect would place one or more counters on a permanent you control, it places twice that many of those counters on that permanent instead.¹
Illus. Wayne Reynolds

Gatherer Card Rulings [Nov 2009]

• 10/1/2005: The tokens and counters that Doubling Season creates are exact copies of the kind of tokens and counters that were being created in the first place.
• 10/1/2005: Doubling Season affects cards that "enter the battlefield with" a certain number of counters. Triskelion, for example, would enter the battlefield with six +1/+1 counters on it rather than three.
• 10/1/2005: If there are two Doubling Seasons on the battlefield, then the number of tokens or counters is four times the original number. If there are three on the battlefield, then the number of tokens or counters is eight times the original number.
