Pseudo-Harmless Cobless

Strategy by 雪漠北
Variable Tempo:    • Pseudo-Harmless Cobless (Variable Tempo)  
Fungi and Flower Pots are not plants (I can't find a proper excuse for Lily Pad). A better name is "No Pumpkin Repair Cobless“

Tempo: Card 2~3 + DPS: Ice | Ice (|) Doom.
The structure is very similar to One Cob Suppression and Rear Cobless, but there are fewer plants and instants to use.
Row 1/2/6 has level 2 DPS. Row 5 has level 3 if you stall Gigas a few times. You have to stall Footballs on row 2/5. You also have to stall Footballs on row 1/6 if they are not slowed down.
I used Cherry to hit row 1/2 and Squash to hit row 6.

Besides the fact that cannon fodders are "harmed", this setup is still "pseudo" because:
1. Because you can't use Jalapeno, the maximum allowed tempo is Card 4 + DPS (Doom | Ice | Ice | Ice). If it gets faster, Ice won't recharge. 1 Permanent Ice spot is not even enough to sustain 2 flags. However, this setup's tempo may get up to Card 5 + DPS (even faster if you use Garlic + Spikeweed). You won't have enough instants against Jacks and Balloons.
2. If you don't pre-judge Doom's timing, you can't use Ice immediately on the second wave (2:17). There will be a 1.5-second delay due to Coffee Bean's CD. Early Jacks can blow up the Gloom on column 7.
3. 1 Spikerock is not enough to 100% kill Imps (if not slowed down). Fortunately, on 5:24, the Imp is killed by the 1-pea damage from Ice.
4. During waves 9, 19, and 20, if row 2/5 does not have Giga or Garg, zombies on row 1/6 will not be slowed down (8:19). You have to use an (or more) extra Ice to stop them. It will be incredibly difficult to defend the front Pumpkin
5. According to PVZ2's definition, if you use an instant, that instant itself is harmed...
Because of these, this is a very controversial strategy. Some even call it "the fake setup".

Mistakes:
5:16 failed to stall Giga
Some cannon fodders are redundant, wasting sun.
8:28 I used Cherry to kill pool ambush on col 6-7, and use Ice to freeze ambush on col 8-9, along with Bungees（冰冻珊瑚帝）. However, the Gloom will be harmed if a Buckethead appears on col 8. The best solution is to intentionally leave 4-8 empty and use Cherry here to kill all ambush on col 7-9. If a zombie appears on column 6, use Lily + Ice to stall it. Then, shovel the Lily Pad on 4-8. Otherwise, Dolphin Riders will jump over and bite the Gloom.

P.S. The 2 Fume + 1 Gloom + 1 Melon structure in Rear Cobless isn't 100% immune to Zombonis, so 雪漠北 uses 3 Fumes.
