I don't think emblem interaction will happen and it would seem silly to make a card for that sole purpose. I mean, I have been an avid legacy/modern player for years and beating/losing to decks that seem to be able to turbo emblem has never been a issue to me. I find getting the slow death from
pox/ponza/eggs decks to be more tilting. I just save my pyro/hydro blasts and red/blue
elemental blasts or
liliana's defeat to counter or just blow it up. For modern I would just save a bolt. And now with all the new cards that remove like 5 counters off a permanent, its my own deck building fault for letting the game go long enough for them to drop a fat walker on the board and lose to "
defeat by emblem". I also just run
stifle/
nimble obstructionist, god is cycling him so good when you get them with that or put the kibosh on a storm trigger, and let them kill their own walker with a failed ultimate.
Pithing needle is also great.
Short story, there are so many ways to deal with planeswalkers when they are on the field or to counter/ make the player sac them that losing to an emblem is just your deck not dealing with it or they had a better game than you.
I don't play commander much so I figure complaining about it in that format is just like saying the sun is to bright, why can't they make better sunglasses.
