1v1 you're considering this:
1-4 type matchups
4 potential moves out of lets just say an average 50 move pool unique to that mon (which changes and grows every gen)
2-3 potential abilities
1 hold item
At least 3 of the mons stats (1 atk, 1 def, spd)
Switch to 5 other potential mons
Now double battles 2x all that AND add in several new mechanics and possible interactions unique to the format
Triple battles 3x it and quad battles would 4x it
Add on to this that each time you go up one mon in battle positioning becomes much more significant
The complexity doesn't just increase linearly with each additional mon you add to the battle
Simply too much to think about
Battles would take forever and feel totally random
At the bare minimum you'd need a whole extra prep stage at the start of battle to show both players the position of the mons at start because that alone is a 1/16 dice roll
