After Alexstrasza if you have Anduin in play then you can ping into mind blast into ping into mind blast into ping for 16 damage with only those two cards. It is used as a finisher and the damage can even be more of combined with shadow visions

The card is just really good. It’s a dragon first of all that can trigger your Duskbreakers and also because of the deal 1 damage AoE it is usually capable to trade favorably with most minions. For example, of your opponent has a misha or a Le’ok on board then by dropping Dragonmaw they become 4/3 and 2/3 respectively making them have to value trade with your minion. You’d be surprises the amount of times this applies. If you want to see it in action check out firebat, he usually remarks why the card is good
