We all have the Thunder Slayer Shirt to create cards like this. We mm should do our best with what we have to create cards that are better than Konami. That doesn’t mean we’ll anyways be successful, but we should try. Trying to cram too many words into a single card isn’t great design, regardless of who makes the card.
Best Thunder Slayer Shirt
Not really. Actually the summon negate effect is not dependent on the xyz materials. Also the floodgates effects depends on the materials used only so even if you detach sekka or rai-oh, if you used Thunder Slayer Shirt as material, the floodgate effect will still remain until thunder slayer leaves the field.
