Phoenixian Cluster Amaryllis

This is my most favourite plant type monster up to date. Most other people use plant effect and support for swarming and destruction but I rather use them for defense and burn. Although this card is card cannot be special summon via Lonefire Blossom and most other cards, but it is rather easy to summon it by having this card and Phoenixian Seed in your hand or can just special this card via its effect. Just dump it in the grave using Foolish Burial, Hand Destruction, Card Destruction, Trade-in or something. As long as you can keep a fresh stock of plant monster in your grave, this card will always return to your field.

Being able to inflict 800 damage when it is destroyed, means your opponent will lose once its effect is activated for the tenth times. Unless of course if your opponent has a effect damage negation ability such as Black Winged Dragon, Dragon Knight Draco Equiste, Life Stream Dragon and so on. Also if your opponent has and outstanding life recovering abilities such as Soul Absorption and psychic monster. Soul Absorption is this card deadly weaknesses, as most likely that the deck contains Soul Absorption would tend to include Dimensional Fissure or Macro Cosmos which will shut this card effect once and for all.

Nevertheless, below are the recommended cards.

You can also include Dark Room of Nightmare to increase the burn damage if you like, but i think even without it, this deck has enough burn damage already to burn even more than 20000 life points.

Feel free to try it.

Laval

Laval is a fire type series which is almost same like other fire archtypes focus on mill and to certain extent removal. Contrary to another archtype Flamvell who's only focuses on milling, Laval is a bit flexible due to the easy milling ability gained from Laval Miller, Laval Chain and Molten Conduction Field.

Like most other fire deck, Laval also receive support from the most favourite fire support card, Rekindling. However, it is only limited to some of the Laval monster which mostly tuners such as Laval Forest Sprite, Laval Volcano Handmaiden and Laval Lakeside Lady. While the non-tuners eligible for rekindling effect would be Laval Lancelord, Laval Magma Cannoneer and Laval Dual Slasher.

Depend on each individual preferences, Laval deck can be build either way. As for removal, it is advisable to include Dustflame Blast to act as a trump card clearing up the field for your direct attacks, but watch out for Stardust Dragon or Starlight Road. Note that Searing Fire Wall can act as a defense, tuning and prevention such as from opponent's Monster Reborn, Autonomous Action Unit or Evigishki Mind Augus. Burgeoning Whirlflame also works that way as its effect of returning it self to the hand can be activated during either player's turn. Sealing Ceremony of Katon also another way, but it also affects opponent's grave as more card that target graveyard or deck with graveyard based strategies. Flamvell Counter also gives your deck the ability to negate troublesome spell or trap at the cost of removing your monster that is which I think actually sets your strategy for Laval Cannon.

Thanks to the easiness of milling from Laval Volcano Handmaiden, Laval Lakeside Lady can bring out its full potential to destroy set card on the field without affecting your hand. The remove monster can be bring back via Laval Cannon, and Laval Cannon can be recycle using The Warrior Returning Alive. An unfortunate Laval Cannon that was removed such as from Bottomless Trap Hole or Dimensional Prison, can be return back through Laval Lancelord. The fact that Laval Lancelord is level 6 making it harder to bring out, even with its effect that allow summon without tribute. This is because it only stays on the field for 1 turn unless if opponent destroy it using Mirror Force, Sakuretsu Armor and so fort which in most case might not be happening. Luckily, Laval Lancelord can be easily swarm to the field using Flamvell Firedog's effect.

Note that Some of the Laval monster are named "Lavalval", it is still treated as Laval monster due the word "L-A-V-A-L-val" is there. Actually same case applies for other common archtypes such as, between Six Samurai and Legendary Six Samurai or Gishki and Evigishki.
