Also, I will take your challenge, waterwarrior. Training items allowed.
Turns out the arena I picked out doesn't allow unevolved mons. So let's go with this;
Field Type: All
Restrictions: All NFE's get the effect of a boosted Eviolite (*2 Def and SpA) without holding one.
This stadium is like the tournament arena. However, there is a break in the bleachers, where there is a large, enclosed white room with a door for employee access. Inside, scientists have built a machine that emits special invisible light rays, that weaker Pokemon (NFE's) absorb in their bone marrow (or something in their body if they have no bones). This increases thier body's stability, in effect giving a boosted Eviolite effect (boosting Def. and SpD by *2). This allows NFE Pokemon to be competitive with FE Pokemon.
This ref is willing to take Ragnarokalex vs C$FP and ref it as a 2v2 doubles.
Arena: Shield Battle Arena
The arena has sufficient external sources to allow all moves to be used, with the exception of seismic moves (Earthquake, Bulldoze, Magnitude and Fissure), Dig, Dive and Grass Knot.
In a quaint little village, this kind of battle is quite popular. The pokemon will stand on large, circular shields held above the heads of designated shield holders. The pokemon must try to maintain their balance on these shields, even if they would normally fly or levitate. Therefore, each pokemon, in addition to its usual stats, has a special balance stat. The maximum this can be is 5 (and this is what it starts at) and the minimum it can be is 0. A pokemon loses 1 balance any time it takes more than 20 damage from a move, it takes a critical hit or it flinches. These stack, so a move that does more than 20 damage, gets a critical hit and causes a flinch can make its target lose 3 balance. At the end of each round, all pokemon still on their shields regain 1 balance.
If a pokemon's balance ever drops to 0, it will fall off of its shield at the end of the action. Once it has fallen off of its shield, the pokemon will forfeit its next action as it gets back onto its shield at the end of that action and its balance is restored to 5. While doing this, any moves that were aimed at that pokemon will not be executed and any multi-target moves will only target the pokemon still on their shields.
