For 2-mana, this is fine
My some of my favorite budget bombs to cheat into play are: Diluvian Primordial, Sphinx of Uthuun, Scourge of Fleets, Tidespout Tyrant, Stormtide Leviathan, Sphinx Ambassasdor, Guile, Windreader Sphinx Bombs and Other Things Some counter spells can turn into game-winning bombs in the right situation
That can be Wurmcoil Engine, and if I have the mana laying around anyways, it's a great use of it
This is certainly a unique and fun design, but not necessarily the most powerful one out there for Grixis
Synergizes best with Hexplate Wallbreaker, Adaptive Omnitool, and for insane token management: Bloodforged Battle-Axe
In more recent versions of FINAL FANTASY VI, Suplex was updated to be called 'Meteor Strike', which is a very cool name
