After much testing this is what I believe to be is the most consistent freeze deck for Rose.
The thing I've discovered and is interesting about the mulligan process is that in the early game players will give rose respect and not play a zombie for fear of the freeze combo
this is what we take advantage of and keeping 3 drops like Rescue Radish and Vanilla are all pretty viable. The beauty of Rescue Radish is that
its great on turn 3 when you have no plants and later on we could bounce back our "When played" cards like Chilly Pepper, Brainana, and The Greaat Zucchini. However, if we have freezing in our hand or snow drop we obviously want to keep that.
Against Gravestone decks Snow pea is a good keep to combat the inevitable Swashbuckler, against crazy decks water balloons are a good keep to kill off low health minions, and snapdragon could be a good keep
to combat zombie heroes without nibble or plumber. These are all very good situational keeps but remember our top priority is freezing, and stalling for our late game finisheres. Most games with this deck will
go to the late game and that's where we rely on our Great Zucchini or Cornucopia to finish the game. Don't underestimate snowdrop however, it very well could be our win condition along with Power Flower if our opponent has no removal in hand
but snowdrop is more of a distraction for our opponent that they have to deal with in the meanwhile before we get to the late game.
At first glance, this deck looks similar to PvZTryHard's "Freeze Rose" deck. However, the way you use this deck is different from that deck. For your information, I tested this a lot on ranked in the early diamond league. It has fared kinda well. To use this deck effectively, you need to keep either your snowdrops and/or your mayflowers alive. Depending on your play style, you might want to either freeze zombies to buff your snowdrops and play mayflowers as a distraction or vice versa. Here's the list of each plant and their purpose in this deck. (As to why I call this version 1, I didn't have winter melon as when I made this card deck but this deck works surprisingly well. If I do add that plant, it may disrupt the deck synergy so it must have its own deck)
Iceberg Lettuce (Used to buff snowdrops and to destroy zombies if a winter squash is currently in play.)
Snowdrop (One of your two crucial plants in this deck)
Snow Pea (An early way to freeze zombies. Also very cheap)
Water Balloons (Well, stat reduction of zombies never hurt plant hero)
Chilly Pepper (like Iceberg Lettuce but you can also defend a lane)
Mayflower (Your other crucial plant. She is going to supply you with extra cards and can also distract the zombie hero)
Spring Bean (A nice way to wipe clean those buffs that zombie earned)
Whack-a-Zombie (You need this to eliminate weak strength zombies. They may cause your downfall if you don't bring this)
Carrotillery (Huge damage giver)
Lawnmower (A cheaper squash that works only on ground lanes)
Winter Squash (A nice way to kill zombies anywhere for just 1 sun, Iceberg Lettuce. He can tank a few hits so he can last a few turns before dying unless he gets hit by deadly)
Squash (Use this if you don't have any other instant-kill options)
This deck is a flower deck which can help controlling the field while gaining sun to plant strong plants earlier. If you don't have the legendary plants i had listed, add other flowers instead. (Any of them! Add whatever you like.) Add 2 Metal Petal Sunflower and 1 Bloomerang if you don't have Witch Hazel
Below is the non-budget version of this deck! Make sure to check out that one if you have the cards to supply it!
This deck is just like Cyclecap. But because this is Rose, you don't swarm, you control. It's just like my budget version of Cyclecap, with some beans on the side. Except, because of the absence of Sonic Bloom, our replacement will be Sportacus. Now, I promised no Super-Rares, but Cyclerose here won't accept that rule, and thus we will be running 4 copies of Sow Magic Beans. No Legendaries though! Keep shuffling them Magic Beanstalks in your deck, and Admiral Navy Bean will keep dishing out damage and drawing you cards. Or Sportacus could be doing that, who knows. As long as they're in a Planet of the Grapes and you have their respective activators ready, then you'll be fine. Sportacus is useless against non-trick decks on the Zombies side, however, but so far I haven't seen a Zombie deck without Tricks.
The budget version of this deck is above! Although, if you have already it, you might not have to read this. If you don't have the cards to supply this deck, then be sure to use the budget version instead!
Now that this version of Cyclerose doesn't have limits instead of the budget version, we can finally work with the cards that makes the Smarty part of Cyclecap work! So this is how it goes: Turn 1, Admiral Navy Bean. Unless you're unsure about its safety, never play it in the water lane. Turn 2, Lima-Pleurodon and another Admiral Navy Bean, control, double ANB, double LP, or Sow Magic Beans! If you don't have any of the combos in your hand, go for control. Turn 3, Planet of the Grapes! Put it wherever Admiral Navy Bean is. If you don't have ANB in the ground lane, don't have ANB at all, or don't have PotG in your hand, go for Sportacus, or keep controlling. Turn 4, it's time to cycle! Put your defenses up, and every bean you play always has backup. Never run out of cards to cycle through with an endless supply of Magic Beanstalks, sponsored by Sow Magic Beans and Lima-Pleurodon! Your late game touch is full of Legendary beasts that roam the battlefield.
Super Brainz had a bounce deck, why not Rose? Between the bouncing and removal Rose brings to the table, your opponent will have a full hand and an empty board until you can obliterate your foes with an army of beans!
This is a chilly deck that will freeze Zombies in their tracks! During Feastivus, a brand new card was added to the Plant side of the battle. She is always in a good mood, even when she's fighting Zombies. Jolly Holly is an Amphibious card who freezes Zombies in the lanes next door when played, and is a great compliment to a strong freeze deck both for control and buffing up a Snowdrop. If you missed Feastivus, don't worry. Jolly Holly should be available next year around the same time. Also, look for Mayflower during Fall Food Fight.
