I understand that you have had an infuriating and ridiculous loss against a Magmar recently. However, merely concluding the meta with an experience from only one game is a little rushy. If you could provide other examples and experiences on how fast the meta is right now, we could continue the discussion with more depth.
Handling threats is a complicated matter - it involves your deck-building skill, anticipation of common threats, and also luck. You anticipate that there will be loads of Magmar who run Chrysalis Burst on the ladder, so you tech in a few Blistering Skorn in your deck. Still, you could do nothing when you couldn’t draw into a Skorn when the opponent poops out 4 random eggs on turn 2. Even if the game is partially dependent on luck, your skill and wit is also crucial. Knowing when to replace for more aggresive plays and when to keep answer cards instead of tempoing it out is a complicated matter that takes a lot of experience to master.
Indeed, sometimes you play against an unbeatable starting hand, and that certainly doesn’t feel good. But you also have to consider that on other occasions, YOU are the one who get the perfect hand to pull off your dream combo on your first few turns. This game is somewhat dependent on luck, and hence some absurdity happens. Those doesn’t happen often tho, so just get over it - maybe taking a few-day’s break from the game would sooth your frustration?
