You can draw cards when used with 'Fearless Lusi, Fang', but
OP04-111-hera makes it so that 12k Linlin, with Banish or Double Attack, can just go ahead and attack again
Wasitora, Nekoru Queen eats a piece of cardboard whenever it hits an opponent, and if the opponent has nothing to sacrifice you get a 3/3 Cat Dragon token
Luckily, there are plenty of mana rocks in this precon deck, ranging from Thought Vessel, Hedron Archive, Thran Dynamo and even a Gilded Lotus to generate lots of mana and serve as attackers thanks to Bello
Thats essentially what Wrathful Raptors does for you
Yes, only drawing two cards from this isnt the biggest hand refill, but the ability to give a large creature trample without going down in cards helps you keep up with the rest of the table
