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.
The reason there are so many of this KoG decks compared to other decks is because it's much cheaper and there's just soooooo many of them ran. Probably deserves a better rating, but you have to look at the win RATE not the number of wins, assuming decks are played properly. I don't know those numbers, I'm just saying the number of King of games Weevil decks alone doesn't mean everything. Also it's not a problem that this deck is easy to play, it's the build that matters, but this deck is easy to play.
The reason this deck is popular is due to the popularity of Harpie decks!
Believe it or not, Weevil decks are one of the strongest counter decks to Harpies.
Most Weevil decks run a Burning land which gets rid of all field spells.
Most of the popular Harpie monsters Sonic Duck or Jerry Beans.
They have very powerful attack.
However, the defense is like 700 or 0!
It is huge problem!
It is like the Ying & Yang!
Mai decks rely on the power of there attack.
Weevil decks rely on the strength of there defense.
It is actually very funny when you think about it?
Harpies try to swarm the field?
However, you can't swarm against Bugs!
They are the ones who invented the Swarm!
