Both me and a friend got it in the first week and were confused about how easy it was this time. We thought there must have been some change to get us through more easily.
I used a Daken Destroy Deck (deadpool and taskmaster did most of the work), He used a galactus/nimrod deck.
Edit: I will say, the Daken deck has been underperforming since hitting infinite, Not sure if that's because of a different meta in conquest or it it's just that i've been getting unlucky with it, having lots of fun with my thanos/death deck currently in conquest.
I think the temperature doesn't work as part of the definition. If you've never had it, Taco Salad is served hot (the meat at least is, and usually the tortilla bowl is as well).
