Nope, the Tournament as such is not as bad as you think it is. Lineup Deepening and Strengthening come into major play, but above all is patience. This isn’t a short term Game that finishes all its glory in 3 months of playing, instead if you’re in for the long grind you will be able to succeed.
Also, Hunter does sometimes match you up with extra powerful opponents, this is admitted — I do not know why but since the last few months I’ve observed occassionally they give you extra powerful matches at times in lower leagues. But don’t judge the entirity of tournaments by these few matches.
Once you get a deep enough Lineup, you won’t be minding the loss of a few creatures to the over powered matchups. This is why I personally recommend you to start the first few matches in lower leagues with level 1 commons, it’s no guarantee that the ferocity will stabilize but just as a preventive measure in case it does.
