Sidenote: NO zombonies in night endless
This is a pretty cool setup but it is actually pretty difficult.
This is intermediate-advanced because you need to know how to cannon fodder extremely precisely and you need to know how to keep a solid card 2 tempo.
Overall I would not suggest you use this setup for a night endless run. I would recommend either frost cobless or group-gloom.
Sequence: Card 2, Doom-shroom + Imitator Ice | Cherry Bomb + Ice 25:25
This is pretty much just a worse version of frost cobless because rows 1 and 5 have very little damage and row 3 is obviously difficult to defend.
Threats-
Giga- Obviously the biggest threat. It's extremely difficult to defend them on rows 1, 3 and 5. Also because of the way doom-shroom works in night, if you place a doom-shroom on row 4, it won't hit gigas on row 1 for some reason so you need to either waste a squash on row 1 or waste cannon fodders.
Jack- Jack suppression in this setup is really really good. You have make sure the ice activates around 2 seconds after the wave spawns in in order to have optimal jack suppression on row 3. They can blow up the front pumpkin on row 3 though which is highly annoying when it happens especially if you can't instantly replace it. They can also blow up squashes.
Football- They are just generally annoying. They help slow the tempo down which is nice but they often get in the way of cannon fodders and I even had an attempt where they ate the front pumpkin on row 3 and ate the gloom.
Diggers- There are only 2 glooms to kill the diggers so the pumpkin pressure is pretty heavy. If you are bad at stalling gigas and you often need to use pumpkin as a cannon fodder, then the diggers might eat their way through the pumpkin before it has a chance to recharge.
Garg- Giga but easier
Sun- I was very delicate when it came to sun in this run even though it may not look like it. I only lost 150 sun which is absolutely incredible for me because I always lose about 5x more sun than I should on card 2 cobless setups. This can easily play endlessly by an advanced player.
