How exactly? It’s 7 mana so no killing edge…
Beside say you deployed it.
Rushing unit —> got killing edge —+> no mana to cast.
turn 8 it’s probably going to eats a heavy fat dispel.
Say you got inner focus, at turn 7 is you still need your inner focus that bad you might just concede.
The only cards you might want to get are juxta, mds or the 8 mana fat finisher.
Kindling will be good assuming it’s not getting dispeled right away, and it will… you better believe it.
