Why oh why, does this always happen?

I hate it!
I was fighting Dark Magician Girl in Tag Force 2 and she was not even a tier 1 duelist but somehow she beat me like 9 out of 10 times.

I was fighting Mako Tsunami in Nightmare Troubadour and he is a 2 star duelist *out of 5* but he beat me like 5 times in a row!
On the other hand I fought Marik Ishtar and he is a 5 star duelist *out of 5* and i beat him thrice in a row!

why do they give wrong rankings for duelists!?!?!?!

I can't really tell you nothing. I've been playing this game for too long and I know stuff like that happens. That's just how it is sometimes! (I can't really explain)

yeah i was kinda expecting that ^_^
if anybody knows why tell me^_^

everyone has there losing moments.
