The official Bard meta is 2 double merc pyras. Plink your enemies to death
Double merc pyra is also one of the ram builds.
Gat carro too...
As for fun builds I use..
Mines.. They're fun.
El Muid with mines (side carro if I only have one mine gunner)
Mine Fish, h-carro front, side mine, may try this with a minotaur too..
Mine Pyra, either double front mine, triple mine or mine carro or mine Gatling...
However I've hardly touched pyra because Squid is too much fun.
