I’m sorry, I’m a bit late with this one, aren’t I
I really, really wanted to let you know how awful it was.
The huge, glaring problem with it is the enormous disparity in power levels been the top tier of Legacy cards (e.g. Prism Array, Rishkar’s Expertise, Blue Sun’s Zenith) and all of the KHM mechanic cards we were forced to play for the objectives (Foretell, Snow, Boast).
This often means that the random matchups provided by the event are completely one sided:
All of the games I played in the event matched my deck consisting mostly of Legacy power cards against decks that seemed to be full of KHM cards. None of my games were a challenge, or even slightly interesting to play. A monkey could have played my games and scored maximum points
Meanwhile, a tiny number of matchups given to completely random players are often against a Greg with a full power Legacy deck; sometimes these Legacy decks don’t even feature the requisite KHM mechanic cards to complete the objectives. Perhaps the player here is also playing with mostly Legacy power cards, so maybe they can outplay Greg; or maybe they just don’t own the cards and get blown out, or maybe even if they DO own the cards, Greg gets a big cascade on turn 1 and wins anyway.
Players get a game loss, and get bumped an enormous number of places down the event leaderboard, simply through a quirk of the matchmaking system.
It’s easy to see one quick way to mitigate this problem: limit the number of sets playable in the DC event. Keep the same sets legal in the event that were legal at the time the event was in Standard. If the event is going to force players to play with many low power cards, then the top tier power level of cards allowed in the event should not absolutely dwarf them.
We did mention this before you ran the event.
What do other players think about Legacy DC?
