Standard format (Japan)

スタンダードレギュレーション

In Japan, Standard rotation is referred to as a スタン落ち (informal term?).

According to JP Wikipedia, the format was introduced in 2003. The page lists every format but there are no sources unfortunately, but Pokumon's articles and some other articles coincide with some of the events or contradict them.

First rotation, Battle Road Spring 2003 (first held in Sunday, March 23, 2003). The original and Neo series were removed from the game, and the earliest legal set is Pokémon VS-on, released in 2001. The set was never released outside of Japan, but it's close to 2003-04 Modified format (TCG) which is Expedition-on. In Japan, this move was due to change in card backing on Japanese cards.

Second rotation, Battle Road Spring 2005 (first held in Sunday, March 13, 2005). VS, Web, and E series were removed from the game, rotated to ADV-on. Roughly equivalent to 2004-05 Modified format (TCG), indicated by the retirement of yellow bordered cards.

Third rotation, Battle Road Spring 2007 (first held on Saturday, March 17, 2007). ADV is removed from the game and rotated to PCG-on. Roughly equivalent to 2005-06 Modified format (TCG).

Fourth rotation, "Battle Road Spring 2009" (held ???). PCG is removed from the format and only cards from DP-on can be used. While it's claimed on JP Wikipedia, it seems that this event doesn't exist. On seesaawiki, it's claimed that it occurred on October 12, 2008, coinciding with the World Championships Japan National Team Tournament.

Fifth rotation occurred at the 2011 World Championships. HGSS-on. According to seesaawiki, this occurred on July 23, 2011, coinciding with the Summer Carnival at Tokyo Tower.

Sixth rotation occurred at the 2015 World Championships. BW-on.*

Seventh rotation occurred at the 2016 World Championships. XY-on.*

Eighth rotation occurred at the 2018 World Championships. SM-on. Occurred on September 1, 2018.

List of Pokémon with an attack cost of 0

In the Pokémon TCG, some Pokémon have attacks with no Energy cost. This mechanic was originally introduced in the Diamond & Pearl series. Originally, any Pokemon could have a 0 cost attack but since the HeartGold & SoulSilver series, the mechanic was reserved exclusively to certain card types.
