I have a fairly detailed write up on my master thread.
Vorpal reaver is pretty crucial to the deck, id honestly probably play something a bit different without it.
Take a gander through my thread, and if you still have questions or want some help budgeting hit me up again.
Questions my write up doesent answer:
Removal is valuable, don’t waste a lure just because you have spare mana. It is ok to not spend all your mana.
You want to use darkfire early, or in combo with desolator, its a safe replace in the mid game.
Inkling surge is a great opening play to contest globes, or if you need to ritual/darkfire, or of course to be used if you have wraiths on board, but no you don’t just use it because you have nothing else to do, again it is ok to not spend all your mana.
Grasp is a tech card you don’t just use it just because. Your not an aggro deck you dont need to push damage quickly, you have the late game. Grasp is to be used to counter various swarm stratgies or walls, and usually replaced the rest of the time unless you can line up a multikill with it sometimes by combining it with lure.
Its important to manage your resources and not just dump as much of your hand as your mana allows, you will run out of cards if you do that.
