Skaven win hard and lose hard. A top tier team not for the faint-hearted. Everything is an opportunity to score with them. They love random effects from the kick-off. A fan throws a rock? Great chance to injure an opponent. Skaven players get injured all the time because of weak armour, so less painful for you. Every disaster that could happen on a pitch is a blessing for the Skaven. Opportunists. Grab every chance. Every time the opponent drops the ball, you score touchdown. Even when 8-9 players are KO or injured, they continue to score. I lost something like 5-1 against Skaven playing dwarves, even though I massacred their team.
For a new player, it is easy to lose your first games with them. They run fast and die fast. A technical team and the fastest team in all of Blood Bowl. Spend your game on the ball and sneaky hit and run attacks. Don't go for mass fights trying to beat up the opponent, because most teams are stronger.
