For lost land:
possible team (double crowd control + 1healer): Lazu & Cosmo (their proc should alternate). Lazu should proc first since lazu is immune to silence. Walla (heal and debuff team), ripper(healing reduction),LW(energy control), DK(debuff opp). Saint warden.
Other comb: double healer (OCC& walla) + 1 crowd control (Cosmo) on the back. Front line:Anu + lava + Phobo. Brawler warden. NB: Cosmo on defend will proc first against your Cosmo. Placing Phobo in the front line can help (his passive silence can silence Cosmo before his proc). Phobo passive silence range on the front line will cover the opponent front and middle line.
