Bonus have changed, new bonus are:

{
    "bonuses": {
        "blockTacticalSubs": 1,
        "boostAllPlayers": 1,
        "boostOnePlayer": 3,
        "fourStrikers": 1,
        "mirror": 1,
        "nerfGoalkeeper": 2,
        "removeGoal": 1,
        "removeRandomPlayer": 1
    }
}

The fourStrikers bonus is new.

It should be managed, but in this case the squad scheme is updated => not simple (in addition for next turn).

Perhaps using it as last priority and only if 4 strikers have a minimal note could be relevant.
