I can see both sides of the argumet here but cant really decide where I stand. I mean on the one hand it is a bit of a nothing moan, its still for all intents and purposes a basilisk. But while a rare occasion it may be, fighting with a fully modelled and painted army is great and adds loads to the experience. If you've made all your troops up, painted them and lugged them to someone elses house to field them the last thing you want to see on the battlefield is a tank made from office supplies.
If it were me i'd allow it but i'd make damn sure i blew it up real quick to get it off the table.
A great tactician knows that victory is one part planning and nine parts faith
