Up until very recently, I've been of the mind that if you are playing against friends in a living room, there's no reason you can't proxy whatever you wish. That was until I was on the receiving end of 3 /D Defenders each with Ruthlessness EPT. It was brutal.
FFG requiring cards would have meant my opponent would have had to purchase 3 Decimator expansions. Not a light feat. Nobody would reasonably do such a thing, so requiring cards limits some broken combos.
Im thinking how to introduce some limits to these lists where players can spam crazy upgrades they would not ordinarily be able to.
What do you guys think?
