I'll pick up
TruetoCheese vs. Birdy (who's still Superbird on the db, by the by.) Also, I have a slot open and really want to try this, so an open challenge:
Format: 3v3 triple
Style: heartbreakingly chaotic, probably
DQ: 2 weeks
Damage Cap: 50%
Banned/Restricted Moves: OHKOs, Super Fang, Perish Song, direct healing except Chill, moves that require nonpresent natural resources
Arena Description: Driftveil Drawbridge. Its attributes aren't anything spectacular, but it will be able to accommodate most first-stage Pokemon; Driftveil authorities have asked that the battlers use only first-stage or non-evolving Pokemon to limit the inevitable damage to the bridge. After adultlike and responsible negotiation with Unovan leaders that did not leverage Asber's reputation for gleeful havoc-wreaking and arena destruction in any way, the bridge will be evacuated and water and air traffic will be barred from passing through on the day of the battle, leaving it open to chaos!
However, the passage of wild Pokemon can't as easily be restricted. Ducklett and Swanna do often pass overhead, as well as the occasional Charizard (don't ask me what they're doing here), resulting in a variety of combat effects. Thus, at the end of each round, one of the following things will happen:
10%: A Charizard flies by and hits every battler for 5% damage.
10%: A Swanna sheds a Muscle Wing, increasing one (random) battler's Attack by two stages for the next round.
10%: A Swanna sheds a Resist Wing, increasing one battler's Defense by two stages for the next round.
10%: A Swanna sheds a Genius Wing, increasing one battler's Special Attack by two stages for the next round.
10%: A Swanna sheds a Clever Wing, increasing one battler's Special Defense by two stages for the next round.
10%: A Swanna sheds a Swift Wing, increasing one battler's Speed by two stages for the next round.
10%: A Swanna sheds an Energy Wing, restoring one battler's energy by 5%.
10%: A Ducklett sheds a Health Wing, restoring one battler's health by 5%.
20%: A Ducklett sheds three Pretty Wings, raising all the stats of three random battlers (excluding Accuracy and Evasion - think Ominous Wind boosts) by one stage. Meanwhile, Charles the heartbreaker rides the wind on the shore and piercingly gazes at the battle with his piercing gaze, lowering the remaining battlers' stats by one stage. If there are fewer than three battlers remaining, each takes one wing and Charles leaves.
Finally, if the drawbridge is damaged, e.g. with area-effect attacks, Clay's Excadrill with infinite experience will immediately interrupt the battle and use Iron Head on the offending battler(s). At the end of the round in which this penalty is activated for the fifth time, the Excadrill will use Iron Head three times on every battler in retaliation before fainting of exhaustion and not interfering again.
Additional Rules: Triple battles restrict the targeting of moves: Pokemon can only target those adjacent to them, barring
certain exceptions, meaning that the order in which Pokemon are sent out matters. In addition, Pokemon to the left and right may also
shift instead of using a move on their action, resulting in their position being swapped with the Pokemon currently in the center. Shifting has 0 priority and, for ASB, boosts the power of Pursuit. (More on shifting
here.) I think that's everything that matters, but the ref and challenge accepter may want to skim the rest of the Triple Battle page just in case.
