The Battle Strength Campaign was a mail-in lottery campaign administered by CoroCoro Comic in spring 2011. There were 1000 winners of this campaign, and each one received 2 sets of 3 cracked ice holofoil promo cards. These cards were alternate art versions of the cover art cards in the Battle Strength Decks.
On March 18, 2011, the Pokemon TCG released 3 Japanese-exclusive half decks themed around the legendary Pokemon Cobalion, Virizion, and Terrakion. Known as the Battle Strength Decks, each half deck included a “How to Play Easy Guide” as well as a “Battle Strength Guide” that included tips for upgrading each of the decks.
To coincide with the launch of these products, the April 2011 issue of CoroCoro Comic included a lottery campaign, known as the Battle Strength Campaign. People wishing to take part in the campaign were required to affix barcodes from 2 Battle Strength Decks to an application postcard included in the magazine and send it back to CoroCoro.
The application period was open until May 9, 2011. The rationale for requiring 2 barcodes was that players would play the decks against another friend, and that the two friends would mail in each of their barcodes to enter the lottery.
Everyone who entered the lottery would receive 2 foldable deck boxes featuring the new alternate arts of the legendary trio.
1000 lucky participants would receive 2 sets of the 3 promo cards in a sealed cellophane wrapper in addition to the two deck cases. The duplicate set of prizes were meant to give to the friend who had entered the lottery with the participant (since it required 2 Battle Strength Deck barcodes). This means in total, 2000 copies of each promo card were distributed.
The text of the letter is as follows:
