Why would 4pc spells be forbidden
Forbidden Combinations

Any capture crazyhouse is another one, Diminishing Returns fits the bill. Another forbidden combo is FFA crazyhouse, which Diminishing Returns also fits.

4pc spells would be forbidden because lets say red blue yellow all targeted green, froze all pieces, putting him into zugzwang, he gets mated early on, so Green is at a disadvantage - increases the king-making leverage.

let's say 4pc freeze, 4pc with only jump is perfectly fine
no - if yellow's queen is lined up on green's king, red and blue apply the jump spell on the two obstacles, leaving yellow free to take green's king on move 1

4pc spells would be forbidden because lets say red blue yellow all targeted green, froze all pieces, putting him into zugzwang, he gets mated early on, so Green is at a disadvantage - increases the king-making leverage.
4pc Spell Chess is perfectly infe -- just hard to execute properly.
