This has about as much kill potential in cube as a Gut Shot and isn't getting a look in as a result

Its particularly nice with Ravenous Bloodseeker, which ensures we can always play it at instant speed, not to mention potentially getting extra pumps

You are much better off trying to kill it

Another easy pair of card types are creatures and planeswalkers, due to the flavor reasoning that they both represent a character

But even more than that, I like interacting with my opponent and to not be totally out of the game if they get a fast start or kill my only infect creature

There are enough of these types of cards that you could lean more heavily toward one than the other if you wanted, but I prefer to diversify just in case
