Gruul Ramp plays almost no blue-relevant spells to counter and dumps big creatures onto the board quickly via Wild Growth and Utopia Sprawl acceleration, so trimming some Counterspell and Spell Pierce for more proactive removal and life gain is worthwhile. Extract a Confession, especially with evidence collected late-game, can strip away their biggest threat like Primordial Pachyderm or Avenging Hunter. Arms of Hadar can wipe their small Eldrazi Spawn tokens and any small, uncast Nyxborn Hydra, though it won't kill bigger threats like Jewel Thief or Primordial Pachyderm, and a bestowed Nyxborn Hydra simply becomes a creature again if the -2/-2 kills the creature it's attached to. Unexpected Fangs helps stabilize combat and race against their trampling threats; keep Cast Down and Snuff Out as your primary removal since they hit nonblack/nonlegendary creatures like Jewel Thief and Eldrazi Repurposer efficiently.
