First off, I should say, I really do love this game. Played since 2018, was VIP for a while, and have quite a large card collection.
However, as of late, I keep facing decks (usually under Teferi, Chronoclast) that nearly always revolve around Ambiguity, in combination with other “lockdown” effects.
Often, I end up unable to play cards at all, or, when I do get a (lucky) chance to board wipe, these denial decks are designed to bring everything back within a mere turn or two. Sometimes, I’m able to hold on for a while, making progress, only for the game to freeze up.
I’ve also had the opponent’s Ambiguity trigger during my turn, so long that the loop timer came up- I stupidly chose to stop the loop, but this only deactivated my own cards!
My first match in Skoti this morning went terribly due to this, dragging on for quite a while (35 rounds!), only to finally freeze up, thus robbing me of the best potential rewards, plus however long I spent trying to win.
Let’s consider for a second, this is all from my perspective: level 306, 6,938 cards collected, and 73 planeswalkers to choose from. Putting myself in the shoes of a new player, I really doubt I could tolerate this enough to keep playing.
Just my 10 cents, and restating some that was posted by others. IMHO, Oktagon left us with some awfully unbalanced design within PMA, and I think denial is the worst of them.
