Some suggestions on what to toss in a bg to help get around tank 2x2 units? I've found my BG really struggles with things like myx broodlord and oakthumpers.
Fumes + Lava & Knockback is the traditional answer to any tough to kill champ. Otherwise just continually disable them or ignore them while going for other key targets.
Unstoppable on these big 2x2 kinda kills the whole fumes thing though that's why I asked if there was something I am missing.
With the high damage values of semiaquatics, you should be able to focus fire them and kill them with reasonable effort. You can use tortun land cannons to help (they are not champions so colossal doesn't apply) or, if you want to tackle the problem directly, you can run swamp doombringers (doom) or elder murkwurms (judgement). But between with cecaelia, songmaster and deflects/diverts you can stall them while running your pirahnids towards the back of his formation to kill the important champions like sandsnipes and matriarchs.
slick and buzz dreadwing potion will eff those 2x2 dumptrucks up. My other proposal is tome of arcanis + circadian enchantress cuz shes a wizard and people dont expect u to do that.
If all else fails, there is Gloomwater to reduce (or raise) DEF to 1. Doesn't help against Tough and such but...
