But they don't have the same speed nor reach as mages. A priest tidal waves and they've reset themselves too, a mage novas and keeps on burnin'.

As for mage vs dc, I told you, did I not? You need burn for 40 damage minimum plus 5 cards at least to sac for resources. DC does not have 40 health. Assuming you're not completely allyless, the gain can be pushed through, and you can safely have a set of Shriek of Vengeance slipped in as some cards you'd be saccing in other matchups.

Do you see, though? Maj has a plan to win. Dc has a plan to win that happens to be good vs Maj. DC is advancing his own goals, nothing more. The only counters you should need is to stop enemy win conditions that directly inhibit your own. Say, acid Jet is a good way to stop KP. SS is just stall and can safely be attacked into.

Nobody needs answers to everything in SE. Simple as that. They all just need to counter decks that are natural counters to their own. Otherwise it's an autoloss. Nothing else is an autoloss. Nothing else demands a counter. I fail to see the need everyone has for having to make extra room in their deck for stacks of situational cards that are only ever wanted in one specific matchup.
