First time I\’m giving a metagame challenge a few tries. Took 3-4 spins and some tweaks, but was able to get the 7-0.
The tweaks were basically put some Jaheira as another good option which can deal with Artifacts and Enchantments, besides Kappa Tech-Wrecker which has low power.
Also went up on Master\’s Rebuke, mostly in order to deal with the new Planeswalker Tasha, but also helped as a good removal at instant speed which isn\’t a fight spell.
Still not 100% on Tenacious Pup, though it helped against Oni-Cult Anvil, giving trample to the several creatures which don\’t already have it.
