If you wanna have some good fun atleast for the lower MMR pick: Lion, Drow, Siper, Lich and TH. Lion and Sniper takes easy lane and should be able to get a kill ones level 6, Drow in mid, and Lich and TH for hard lane. This is a really good fun and working combo, Lich as Support with Mek ofcause and the lovely AoE Ulti and combine that would TH Ulti... sweet times.
