there is one thing i haven't seen here, play Burn is "easy", but play it properly is a very difficult thing

for example if your opening hand is something like this
2 land , 1 lavamancer, 1 vexin devil, 1 bolt, 1 riftbolt and 1 chain
many people think, great i have 9 damage point in turn 2 but, few people see that hand and say, great i have 2 land and 5 spell i can play
