I use Princess Plants ability to flood the board on T1 and abuse sunflower and autumn leaves synergy to punish my opponent for attempting to break my board. I accomplish this using a Rikka engine with petal, glamour, and snowdrop I can easily fill my board T1 and survive until T2. On my T2 I use my non-rikka plants' effects to fill my board and bring out an untargetable Chaos BLK.
If I have solemn judgment in my hand T1 xyz summon Rikka Queen so that I have a way to break my opponents board via her effect to tribute an opponents monster(quick effect) and solemn judgment being able to negate just about anything else.
The weakness of this deck is that the only protection it has, from spell and trap cards that target and remove a monster, is an effect monster and requires 1 tribute.
