Vikings vs Portuguese on Arena

Hi guys, played a game on the ladder (shout out to the guy if he's on here, gg), where I got all the relics, had all the map control (casltes up on all the neutral golds/stones bar 1 I think), and mass organ guns with a bunch of trebs just destroyed me! 11

So my question is, what counters organ guns, I tried arb to start with, then teched into cavilier, then trash + cav, by that point i died! Any advice?

*edit I should add, he had I think three feitoria in his base as well which explained why he wasn't running out of gold
