The XYZ card design is very fair and simple to understand, but not completely simple to the point where it's uninteresting.
Matching levels is very simple
it's insanely so and it's quite uninteresting as a result
Synxhros added a whole card type ie tuners
and because you add up the levels to make the synchro, you need to have some awareness of what cards to summon
with xyz, it's just brain dead
you know full well for every card, it's two lv 4s or two lv 3 or whatever else
There's a reason they are the type of monster with the least banned cards (Synchro's might have fewer now Denglong is unbanned, idk) - it's because they're the most well designed on a basic level across the board.
The ban list is not generally reflective of what cards are insanely broken and which ones are not
lol
Unless your saying stratos is anywhere near as good as some of the more recent cards
99 percent of these cards are entirely dated
Yata even got unbanned at a recent point and nobody has been beating it
cause yugioh follows digimon and dbz logic each new set needs a new more powerful form for the tcg to use and because of that weaker forms are no longer relevant
And while that may be fun to watch in a tv show for that to work in a game just means next to no player input which is kinda important in a video game
