I started playing Inkmoth Nexus and Kessig Wolf Run combo and I liked it, then after looking it up online discovered it was beeing played competively and took some ideas from the winning decks and added some of my own. It has been playing well so far but I could always use some input.
Blasphemous Act helps wipe the board before attacking with the Nexus and it's specially good for dealing with big creatures like Sun Titan, Wurmcoil Engine and such all in one fell swipe. I decided on this over Slagstorm since it allows me to kill big creatures and not just small ones, it also becomes cheap pretty quick in the game, having played it for only 1 red mana most of the time.
I had to decide wich kind on Garruk play on the deck, I started it off with Primal Hunter, but then I got my hands on some Relentless and it worked pretty well too, both Garruks serve a different purpose so I decided to have a couple of each:
Garruk Relentless is abit faster than Primal Hunter and it helps have cheap 1/1 blockers with deattouch, and tutor a Primeval Titan or a Wurmcoil Engine while dooming a Viridian Emissary or a Solemn Simulacrum fetching you a land or a card. It can even pump the Nexus with his cheap third ability
Garruk, Primal Hunter helps have 3/3 chump blockers AND refill your hand
The sideboard is pretty standard but helps get the job done. Autumn's Veil helps keep your game steady agains U Control and Apostle's Blessing helps pave the way for the pumped nexus.
I liked Bramblecrush since it allows me to destroy planeswalkers, something the slime can't do so I'm considering it as a sideboard
Finally, Kessig Cagebreakers used to be in the deck and every now and then I put it back, it helps wonders as it fills your board pretty quickly with chump attackers/blockers that'll keep the opponent busy while you prepare your game
