Especially in PvP, nothing is better than playing it first hand to understand it. For me, one of the hardest part was the nervousness of playing. after playing for awhile, the nerve died little by little allowing me to understand the PvP game better.
i think santa claus is a card that is played more for its abilites than stats, because for 200 those are terrible stats compared to most cards. and even its ability is not up to par for a legendary card.
