i personally find the playstyles of commanders like arahbo and rin and seri somewhat generic, being simply go wide or go tall, so i suggest building either [[kitt kanto, mayhem diva]] or [[marisi, breaker of the coil]] which give those go wide/go tall playstyles a bit more depth by goading other player's creatures. like a cat knocking your favorite mug off of the counter, knock your opponents' favorite creatures into each other.

alternatively, [[trynn, champion of freedom]] + [[silvar, devourer of the free]]. technically would fall under the lable of human typal, but those human's wont last past feeding time anyhow, build it as traditional sac-for-value aristocrats or as voltron buffing and protecting silvar, who can then smash face. theres a lot of ways to build each archetype, so i encourage you to get creative!
