What is an interesting combination of civs you like to practice with?

Just picked this back up after many years so I guess I'm nood status because all the civs besides the originals and conquerer expansion are new to me. So, I would like to mix and match different civs in 3v3 and/or 4v4 and I thought what better place to get an idea than from this wonderful community! I feel like the Portuguese (playing as), Goths, Italians, and Slavs really compliment each other when in comes to spamming strong infantry. Let your thought reign free yo! Give ya boi some setups to try out!
