Arena: Shape-shifting Arena
Field Type: Varies
Complexity: Medium
Format: All
Restrictions: Varies.
Ref Instructions: At the beginning of the match, a random field will be selected from the options below. Every time a Pokemon is fainted, the arena will change again at the end of the round. If more than one Pokemon faints in the same round, then the arena will change only once. Each arena has an equal chance of being chosen. Once the arena changes, all Pokemon will automatically teleport to the center.
The arena is 50 feet wide and 70 feet long. At the beginning of the match, and after a Pokemon is KO'd, the arena can change into the following:
Grass / Standard: The arena is covered with soft grass. The soil is loamy, and Pokemon can dig on it. There are no water source.
Desert: This arena has sand all over it, with a few sand dunes here and there. Although it is possible to dig in the sand, Pokemon who are not of the Ground, Rock, or Steel types may find this a bit difficult. In the center of the arena, a small oasis appears. This oasis is 15 feet deep and 10 feet in diameter. That is not a lot of water, so trainers are advised to use Surf carefully!
Water: This arena is almost completely underwater! There is about 10 feet of space from each side of the arena that is not underwater. In addition, there are three "islands", each with a radius of 10 feet, that are not underwater either. One "island" is at the center of the arena. The other two "islands" are 20 feet directly north and south, respectively, from this center "island". Since these "islands" are made from concrete, it is impossible to use Dig on them. The water itself is 40 feet deep.
Winter: The whole arena is covered with snow. The snow is about 6 feet deep. There is a frozen lake at the center of the arena, 15 feet deep and 30 feet in diameter. In addition, it is also snowing (not hailing), somewhat lowering visibility. Weather moves are permissible, though it will start to snow again once the weather effect is over.
