Yeah that makes sense. At least the idea behind the solution. The thing is that graveyard hate is often binary. Either the graveyard thing is working or it isn’t. An example could be either delirium is active on
Ishkanah, Grafwidow because there are four or more card types in the graveyard or delirium isn’t active because there are three or fewer. Another example could be either the flashback spell like
Firebolt is available to be cast from the graveyard or it isn’t. Same with reanimator targets. There are exceptions to this like
Emrakul, the Promised End or the escape mechanic but they are far between. However we players sometimes like to fight over the graveyard so what is the solution?
Wizards have taken three different paths to solve this conundrum.
Sometimes they make cards that only exile a small amount of cards at a time. And usually for a cost like paying mana, tapping or attacking. This could be cards like
Deathgorge Scavenger,
Graveyard Trespasseror
Deadeye Tracker. In my opinion these cards are pretty well suited for most cubes that aren’t high power but not well suited for high power.
Sometimes they make cards that exile the entire graveyard but then it is also the only thing the card does. That means the card is a dead draw unless it can serve that specific purpose. Cards like this are often designed for formats like Modern, Legacy or Vintage and not for limited formats. Two examples could be
Rest in Peace and
Leyline of the Void. It is my opinion that these cards are not well suited for most cubes that aren’t high power but can be suited for high power. Or cubes with a high focus on the graveyard.
Sometimes they make cards where part of the effect on the card is to exile cards from the graveyard but doing so leaves the card at only half power or you are giving up something else. If you choose to exile with
Callous Bloodmage then you are giving up card advantage. With
Erebos’s Intervention you are giving up life gain and a removal spell. It is my opinion that these cards (like the first catagory) are pretty well suited for most cubes that aren’t high power but not well suited for high power.
I would look into one or both of the lower powered solutions if I were you.
