I tried to play some Magic back in the day when I played YuGiOh... but I didn't get into it.
It was mostly the mana mechanic. I wasn't used to that, so even if I minded it I kept getting dry of resources because I tended to play too aggressively anyways.
And when I didn't... I didn't get anything to spend it on either and lost before I could do much. I couldn't figure out a good balance between resources and firepower.
Then again, maybe I am completely wrong. I don't know anything about the game, after all.
