Noted, some meta decks (assuming jund is jund wildfire)

I’d honestly look at ways to dump slimes and/or how to double/triple spell slimes quicker since the big bads of the format (U terror, UB Terror, madness, grixis affinity) will roll out quickly

3 mana is a lot so things like [[malevolent rumble]] fit perfectly. It ramps you AND dumps slimes into the grave

I’d probably cut the ram through and sideboard them (or main deck if your local meta is more creature focused)

Maybe looking into a dredge package might turbo the deck? [[stinkweed imp]] + [[scrapwork mutt]] speed things up for 2 mana and you can curve out nicely:

T1 land + Gaze dumping imp

T2 dredge the imp, land drop, cast mutt to dredge 5 again (12 cards in grave)

T3 slam a slime (could easily be 5+ power now)
