Flower Cardian FTK

Somewhat basic Flower Cardian list, loop copies of Willow and Moonflowerviewing until you win;
card choices and ratios can be changed as follows:

->Extra Deck: 3 MFV + 1 Lightshower is the minimum requirement for your deck to function, however more flower cardian synchros are good for consuming excess recources that clog the board after you get locked into Flower Cardians or actually playing Yugioh if the FTK fails (+ every Lightshower burns for 1500 on draw, so often you can still save a failed attempt)
Super Starslayer TY-PHON - Sky Crisis is here because sometimes it can break a board going ssecond, Haggard Lizardose can turn copies of Flower Cardian Cherry Blossom with Curtain into an extra draw if you didn't open any tuners. The rest of the non-archetype extra is there to let you turn a hand of Super Koi Koi + nothing into at least something

-> Main Deck: Some people prefer Gravity Collapse over Synchronized Realm , however I think the FTK (even though it is more complex to execute) is more "viable" against more strategies, but play what you prefer
Other Cards, that could be cut down to less copies than I am playing are: Flower Cardian Maple with Deer - Flower Cardian Clover with Boar - Flower Cardian Willow with Calligrapher - Flower Cardian Peony with Butterfly - Flower Gathering - Super Koi Koi - Super All In! , youd replace them with any of these cards that are not already at 3 in the deck or Flower Cardian Paulownia - Flower Stacking 
The main reason for me to not play either of these cards is that Paulownia is (only) a free summon that does not do anything (which some like, as it cannot mess with your combo, but in my experience, the extra draws are often needed), while Stacking rarely makes the difference between achieving your combo or not, in testing it often came in after I had already failed or the combo became self sufficient
Also the reason I play 3 of both tuners is because one of your main fail conditions is not finding on early enough, they can somewhat clog your hand/field later on, but by then you should be able to deal with that.

To finish things of, some reminders of varying importance that I could have used while learning the deck:
- Recardination only summons if it returned a card to the hand, also it can summon any monster from hand
- Flower Gathering cannot summon tuners because of stat lines, get 1 to hand/field before playing this card; also it is your only card that cannot be used the turn non-"Flower Cardian"s were summoned at any point, all others only lock you for the rest of the turn 
- -De-Synchro cannot revive most main deck monsters, unless they were first summoned by their own effect
- Super Koi Koi negates your Tuners effect to treat all material as level 2 for a synchro summon, Tuners summoned by this card can can easily clog your field, use them or tribute them
- Flower Cardian Pine is low enough a level to allow all your free summons form cards like Flower Cardian Cherry Blossom , if you can afford the space, it pays to keep one on the field
- Flower Cardian Willow is the main enabler of the deck, always keep one in rotation
- Flower Cardian Lightshower prevents Super All In! from destroying your field; if you can, set one up early
