-2/-2 is already a reasonable removal spell for the early game, but you can easily sacrifice a throwaway artifact/creature to kill just about anything in the format
6 Academy Manufactor Theres only one line on Academy Manufactor, but it does some incredible things with it
What about a Burnished Hart
In both these formats, the incredibly useful counter protection can be a godsend so its no wonder theyre so expensive
If you can give it indestructible, its just Plague Wind, but a 10/10 that picks off a couple of small or mid-sized threats is still pretty darn good
5 Slime Against Humanity Gettin Too Old For This Ooze Three mana for a 2/2 isnt a great trade-off, but as you cast more and more of this card, youll see better and better returns
