Trampled Again

I love my normal summons. 
Especially when I can normal summon Lonefire Blossom as many times as I can gain NS every turn!
Grab any plant with just a normal summon!

Use Cucumber Horse and Rikka Petal to loop, grabbing any monster you want out of the GY during every battle phase!
Revive Mardel, Generaider Boss of Light  -> grab more Plants from Deck
Revive Cattycorn -> Grab more Field Spells
Revive Fairy Archer Ingunar -> More Monsters!
Revive Sunvine Healer -> Gain LP!

Party to your hearts dreams! Being sent to the GY is not the end of it!

Turn 1 Combo: 3 interruptions + Cucumber Horse in GY

Sunavalon Bloom Predaplant Dragostapelia Teardrop the Rikka Queen 

This is deck for Domain Format. https://discord.gg/jGkRCJkt3d Join the Discord if you wanna see more!

Intro

Let’s abuse the power of soft-OPT Lonefire Blossom  with  Normal Summoning  it over and over from the DMZ!
I’ve added the new Circle of the Fairies , the monster Aromage Jasmine , as well as copious amounts of Double Summon, because each copy becomes just an Emergency Teleport for plants by normal summoning a Lonefire from DMZ!
In addition, I feature Cucumber Horse Looping Mardel, Generaider Boss of Light in my deck, abusing the large # of battle phases that will occur! (To add a plant every time Mardel is summoned)
Rikka Petal will summon itself out every End Phase! The free body allows for easy resource advantage turn after turn.

Plants have several strengths that translate well into Domain:

1. Swarming the Field/searching the deck
2. Summoning From GY
3. LP gain

All of these are present within engine and easily recurable, tied together by the powerful normal summon-able Lonefire Blossom 

Main Combo

My starting board will consist of only 3 interruptions, but also sets up a loop of Rikka Petal , Mardel, Generaider Boss of Light , and Cucumber Horse  working together to add 1 plant monster to hand in every battle phase that occurs.
This will allow you to mount a powerful comeback on your turn: summoning out many of the searched plants, accessing destruction effects, and generally maintaining a resisliant board.

Turn 2 Combo

You would like to use Lonefire to grab Fairy Archer Ingunar out of the deck, in order to revive either your Predaplant Dragostapelia  (if dead) or Circle of the Fairies  (to extend)
Once thats done, (by its own effect) summon out the Rose Girl / Spore you searched, and go into a synchro play! Use Rikka Petal to add Primula the Rikka Fairy to fix levels. Making Aromaseraphy Sweet Marjoram  will allow you to have Blessed Winds , which recycles your plants and revives Aromaseraphy Jasmine . Or you can go into your other options! Theres lots of explore!

Alternate Combo

In the case you are either unable to or unwilling to do the Main Combo turn 1, here is an alternative:

1. Normal Summon Lonefire Blossom.
2. Tribute itself to summon Cattycorn.
3. Add Generaider Boss Stage through Cattycorn's effect.

This will allow you to use Mardel, Generaider Boss of Light's effect twice before it comes back around to your turn. 
Suggestions on what to search: Predaplant Byblisp, Rikka Princess, Cucumber Horse 

Doing this Alternate Combo will not interfere with your ability to do the Main Combo on the following turn. 
Apply one or more of the following adjustments:

• Instead of searching Mardel, Generaider Boss of Light with Aromaseraphy Jasmine, instead search out Predaplant Bufolicula.
• Instead of using Snowdrop the Rikka Fairy to target Mardel, Generaider Boss of Light to make all monsters lv9, instead target Predaplant Dragostapelia making all monsters lv8 and summon Teardrop the Rikka Queen.
• (If Cucumber Horse was searched) Instead of using Rikka Glamour to search out Snowdrop the Rikka Fairy and Cucumber Horse, instead search out Snowdrop the Rikka Fairy and Therion "Lily" Borea.
• (if Predaplant Byblisp was searched) For cost of Predaplant Ophrys Scorpio, discard Predaplant Byblisp to add Predaplant Bufolicula instead of searching out Predaplant Bufolicula using Mardel, Generaider Boss of Light

Additonal Tips:

() Cucumber Horse can revive from any GY, not just your own
() Predaplant Dragostapelia is not hard once-per-turn, and its negate is permanent. Send it to GY for Cucumber Horse cost, then revive it immediatly using Cucumber Horse's effect in order to use the negate twice in the same turn.

() If unable to combo the first turn, Lonefire Blossom -> Cattycorn -> Generaider Boss Stage is good for future setup. Summon Mardel, Generaider Boss of Light through Generaider Boss Stage effect. On the next turn, summon Loptr, Shadow of the Generaider Bosses to tribute Mardel and summon Vala, Seidhr of the Generaider Bosses who revives Mardel, Generaider Boss of Light . This allows you to use Mardel, Generaider Boss of Light's effect twice, though not in the same turn. 
() An alternate backup first turn plan woudl be Lonefire Blossom -> Naturia Camellia . This guarentees Naturia Sunflower to be revived the next turn and secures you a negate every turn. It is however MORE RISKY due to random mills potentially hitting your combo pieces. This plan is better used as an extender if fortunate enough to have an additional normal summon.

() Setting Pendulum Scales allows us to special summon our deckmaster, Lonefire Blossom , one additional time per turn.

() Sunavalon Dryas can mitgate effect damage, but only if you have recycled your Sunvine Thrasher back into the extra deck.
() If in dire strats, looping either Rikka Princess for negates or looping Aromaseraphy Angelica for LP gain is valid.
() Rikka Petal can only revive itself if there are no non-plant monsters on your field. If Vala, Seidhr of the Generaider Bosses or Loptr, Shadow of the Generaider Bosses  were used, remove them from your side of the field as soon as possible.

Enjoy planting!
