Pure 20 Cob | Survival Endless

! Note: Limit setup - too much sun loss.
Really cool setup made by @AdvyPvZ , who also recommended me to play it for myself. I could beat that easily in under 30 minutes, but I haven't noticed for like 2 hours that it's NECESSARY to firstly use ice and then launch cobs, so the wave won't start too early.
Gameplay is really enjoyable to be honest when knowing how to play this properly. No imp intersection is needed.
I didn't bringed pumpkins on column 9 pool because they seem useless honestly. With proper pre-cob water zombies can't do shit to ices.
Sequence: ch6, PPDD | IPPdd-PP | PPDD | IPPdd-PP ( 6 | 12 | 6 | 12 )
Threats:
There aren't any threats really if u play this setup properly. But to be fair sometimes Gigas when I didn't paid enough attention crushed my front cobs before wave 10, and Pole Vaulters can evade your cob if not launched properly. Other than that - no threats.

Add a gloom shroom on an empty plot to contain the imps

[@vex4lion]

The whole point of this setup is to not use gloom and kill imps manually with cobs though
