It doesn’t matter if you’ve been playing this deck in real life or official tournaments. The text of the cards doesn’t lie. There isn’t a mistake. This is how the cards work.
Summoning conditions are not just ignored like this. I will re-state what I said before. The cards, "Flower Cardian Willow with Calligrapher”, “Flower Cardian Pine with Crane”, “Flower Cardian Paulownia with Pheonix” and “Flower Cardian Zebra Grass with Moon” do NOT Ignore Summoning Conditions.
The cards literally state: If this card is Special Summoned: Draw 1 card, and if you do, show it, then you can Special Summon it if it is a "Flower Cardian" monster..
As the card states, if you draw a “Flower Cardian” monster, you can Special Summon it, if able. It does not ignore Summoning Conditions. When you see this text on the “Flower Cardian” monster you draw: Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) by Tributing .
This directly states that it Must be First Special Summoned from your hand by Tributing a Flower Cardian monster. It does not matter if you draw it. Only if you drew the card with Moonflowering, are the Summoning Conditions ignored.
If you still don’t agree, here is the official ruling from the Konami database. This supersedes anything your local judge says. You are free to show this to your judge and ask as well.
