Actually most everything in this meta.
I haven't been around pre-Homecoming, but the game seems to be more powercrept than ever before. It hurts.
It got to the point where there're a few powerhouse card combos and digressing from them on ladder (even memeing up your otherwise meta deck a bit) leads to 100% defeat, except for when your opponents make stupid mistakes. Control-heavy decks are allowed to pointslam really hard, even though control/points are supposed to be a zero-sum game in deckbuilding. Double Ball and Triple Duel both were a terrible warning, and yet here we are again, and it's worse than ever.
That said, SY is the worst offender in terms of annoyance. Most spenders are effectively engines, and for some reason they're allowed to be both tempo and greed cards with minimal preparation and almost no usual engine risks. Coins and great spenders aren't hard to come by nowadays, and this advantage of explosive points is no longer held back by somewhat poor final points evaluation. Now it's just broken. Whoreson might well be the most overtuned card in the game in the sense he does far too much stuff all on his own.
It's time for either taking a break till the next expansion or just throwing a milly fit.
