For a long time, wild cards were supposed to be used on land but that didn't work out that well. Now, why would somebody invest in cards if he knows that a couple of years down the road, these cards will be useless...
People will now fear the new set, because they know what happened to those before. Untamed is the example we have, next will be Chaos later on Rebellion will follow if nothing changes.
Once sets go into wild, there will be hardly any demand for them and prices might collapse.
Yeah, unfortunatly if nothing is done that's the future of the Modern Collections.
