The question should be "Why do something like that? Maplists are also a thing..."

As fo the code.. I would do something like

PHP Code:

new Handle:g_hBadMaps;
new Handle:g_hLegalMaps;

public OnPluginStart()
{
    g_hBadMaps = CreateArray(64);
    g_hLegalMaps = CreateArray(64);
    
    PushArrayString(g_hBadMaps, "de_dust2");
    PushArrayString(g_hBadMaps, "de_inferno");
    PushArrayString(g_hBadMaps, "de_train");
    PushArrayString(g_hBadMaps, "de_mirage");
    
    PushArrayString(g_hLegalMaps, "de_vertigo");
    PushArrayString(g_hLegalMaps, "de_dust");
    PushArrayString(g_hLegalMaps, "de_aztec");
    PushArrayString(g_hLegalMaps, "de_nuke");
}

public OnMapStart()
{
    new String:sMap[64];
    GetCurrentMap(sMap, sizeof(sMap));

    if (FindStringInArray(g_hBadMaps, sMap) != -1) {
        new i = GetRandomInt(0, GetArraySize(g_hLegalMaps));

        GetArrayString(g_hLegalMaps, i, sMap, sizeof(sMap));
        ForceChangeLevel(sMap);
    }
}
