Why can't I Fusion Summon Gatling Dragon with any 2 monsters on the field with my Flash Fusion? Shouldn't I be able to summon any Fusion monster that can be special summoned with Flash Fusion if I have enough monster cards on the field?
The monsters on the field still has to match the requirements for the fusion monster you're trying to summon you moronic 🔥. flash fusion never said that you can just fusion anything you want.
Maybe one day konami will make a fusion card that caters to your brain-dead "logic".
It's worded in the exact same way as literally every other Fusion Summoning card that uses material. There is no logical reason to assume you can just use any random-ass monster. It doesn't even specify how many monsters to use if that were true, so there really is no logic to assuming that.
