What is a good Yu-Gi-Oh plant deck?

Answer 1

fairyking truesdale and gigaplant are a must. but to make it easier here:

Plant monsters were, until Phantom Darkness, a very unsupported Type. The general strategy for Plant-Type monsters is to swarm the field using cards like "Gigaplant", "Lonefire Blossom" and "Lord Poison", but also using cards that summon tokens. They can go hand-in-hand with Insect-Types as well with cards like "Arcane Archer of the Forest" and "Prickle Fairy". The most usual Attribute associated with Plants is EARTH or WATER but they may be of any Attribute. Recent support from Crossroads of Chaos also alters Plant-type strategies to include effects that summon tokens to the opponent's side of the field (Black Garden) and trigger on or cause the destruction of fellow plant-type monsters.

Some of the more commonly used Plant-Type monsters include "Mystic Tomato", "Homunculus the Alchemic Being", "Dandylion", "Botanical Lion", "Lonefire Blossom","Tytannial, Princess of Camellias", "Gigaplant", "Nettles" "Lord Poison" and "Rigorous Reaver".

Plant monsters were previously very overlooked and weak, until Gigaplant was introduced. Even then, plants weren't very strong and well-used. However, massive support to Plant-Types began to be released in Crossroads of Chaos and have been continuing further on Crimson Crisis and in the Raging Battle booster sets. These cards are the ones being used by Akiza Izinski herself in Yu-Gi-Oh! 5D's.

The strongest Plant-type monster is Tytannial, Princess of Camellias at 2800 ATK along with the power to negate any card effects that target simply by sacrificing a plant-type monster (which in worst case scenario can even be herself), not to mention the fact that she can be summoned as easily as tributing Lonefire Blossom on first turn. In power and strategy she is followed by Gigaplant with 2400 ATK and the power to bring fallen plants back to life from the graveyard. When combined with Gigaplant, she can easily stop any targeting force on the field, and in case of cards such as Lightning Vortex or simply your own Black Rose Dragon's effect, she can be brought back with a Gigaplant or better yet by the effect of Plant Food Chain

Plants also have Plant version of Staple cards like "Solemn Judgment" and "Mirror Force", in the forms of "Pollinosis" and "Wall of Thorns," respectively.

Plant cards usually revolve around swarming and regenerating back onto the field - unlike Zombies, however, these Plants are often used to fuel effects such as negations rather than for strictly attacking purposes. They have many cards that allow them to be special summoned to the field from the deck and hand but mostly from the graveyard. Cards like "Lonefire Blossom", "Plant Food Chain", "Lord Poison", "Gigaplant", "The World Tree" and "Miracle Fertilizer" all add major support to bringing back a swarm of weeds to annoy your opponent and often overwhelm them.

Quickdraw Dandywarrior is still a solid tier 2 deck (once @ tier 1, but went down due to the limiting of the deck's essential cards), chaos plants dominate the game right now (along with junk doppel which I built and does xtremely well), Naturia Plants is the best Naturia deck and is worth a look (What I'm building), gigavise, plant beatdown/lockdown, etc. make great use of Skill Drain, and any deck that can place the basic plant engine (spore, dandy, tytannial, glow-up, and lonefire) within it are your best plant decks. Look them up and give them a try. Good dueling! 7 years exp.
