Daytime Group-Gloom Cobless 20 Flags Runthrough

My discord:   / discord  
Analysis and demo:    • PVZ Advanced Guide: Daytime Group-Glo...  

The first 10 flags were very bad, so I decided to play 10 more flags

Dealing with emergency situations:
1. Losing the 3-7 Gloom
If there is Zomboni, you basically lose. There's no way to stop them on row 2/4.
If not, it's still playable. Follow the sequence of NE Frost Cobless: Ice - Doom | Ice - Cherry. Use extra Ice and cannon fodders to control Gigas. Also, make sure the Doom is not bitten by other zombies
2. Losing one 2-6/4-6 Gloom
The corresponding side's DPS will drop to about level 2. Try to arrange an extra Squash/Cherry/Doom. If you have enough Ice/cannon fodders, you can try to stall Gigas to level 3. You will probably lose the front Fume, but try not to lose the Winter Melon
3. Losing a side Fume
If there are no Jacks, play normally.
If there are, and unfortunately, they blow up a 2-6/4-6 Gloom, follow 2
4. Instants eaten/blown up by Jack
If there are Zombonis in the center, the central Gloom is dead, and you lose. If there aren't, try to arrange instants and use more Ice and cannon fodders. On the central 3 lanes, you must bomb Gigas at least once. On the side, you can stall them to level 4 DPS

The plants in parentheses are optional or replaceable
For this lineup, if there aren't too many Footballs/Diggers, I would use double Puff instead of double Ice and use early Ice on the second "slow" wave. Of course, you can still choose late Ice if there are too many Footballs or Diggers. Double Puff is cheaper, while double Ice is more stable.
If there are no Zombonis, you don't have to use Jalapeno. Stall zombies in the center and wait for Squash to recharge.
A "just broken" Pumpkin can withstand about 3 Diggers but not more than 4. From my experience, as long as there are Gargs slowing down the tempo, Diggers shouldn't be too big of a problem. If the tempo is faster than that, freeze the Diggers occasionally.
