Some small correction: That's not Vayu Turbo, that's Blackwing Vayu, which is much closer to Blackwing btw. Also, that's Hero Frog, although tbf that's like a variant of regular frog Monarch, but with beefy Warriors And Fusions. It's just amazing how the meta of Edison has evolved so much, considering how Hero was once ignored, then they took Tengu knowledge and applied to Edison resulting in 5 or so of the best decks, including one wity an engine that also was kinda ignored back in the day in frog. Good thing it's not like Reaper format who was good up until people realized how OP Cyberstein OTK was or HAT who has Soul Charge at 3, but like "There's lots of decks that were better than expected but couldn't explore before".
Yup, YGO players don't read... Because if they would they would know costs aren't negated and the bounce is worded as a cost. I did that once, then read the rulebook and indeed is a legal play. Silence effects are weird in this game.
