Before the last maintenance i play a lot and i never experienced any softlock.
After the la sta update, it became rare, on rule of thumbs every 10 games.
3 times in node of power.
Teferi master of dominaria, 3 ability bouncing tokens. Softlock.
1 time phtflb with garruk on phtflb turn.
The softlock was caused by the viscious wolf tokens (ability three) of my Garruk, Cursed Huntsman killing the Major Karn’s Construct token of the opposing Karn.
I had won all other fights of the event and dropped from rank 1 to somewhere below rank 200
The “bugs” section of forum has dozens of new threads every month. And it’s just a tip of an iceberg - I personally know of another dozens of things which do not work (including cards which do different things from what their descriptions say), which are just not worht submitting as the bug submission mechanism is pain in the bottom.
And then, regularly, we also get serious bugs which break games, make people lose ranked games and because of that, make them angry.
Cards are broken, descriptions are broken, mechanisms are broken, game timer is broken, game UI (user interface) is broken, bugs submission form is broken, even the new forum was broken.
