So many weevil burn decks I see fall short of really good synergy. In mine I added some cyber dino's so that I can chain jade whistle + special summon them pretty much every time. Also use insect princess to quickly stack attack from the other monsters being turned into insects.
Tea is a luck based burn deck.
This is a skill based burn deck.
It's pretty hilarious all the saltyness. Get over it. This deck isn't easy to play at all. Compared to most decks out there this one requires strategy. If it's so effective it's because there's way too many harpy players out there and weevil is a damn good counter due to burning land. What's really bothering you peeps is that your oh so awesome deck lose to this clever deck.
