Why no one includes MYSTIC PIPER in farm decks? It has so much synergy with WONDER WAND, inst-draw 2 cards. If you can also use the Gravekeeper that looks like Odion, thinning the deck will be a bliss!
It's basically a worse Jar of Greed aside from being an extra Wonder Wand target, which is unnecessary once you draw a Recruiter anyway. Crystal Seer's also better at that job, and is lower-rarity, and thus easier to obtain.
Simply put, people don't use Mystic Piper in grinding decks because it's not worth using Mystic Piper in grinding decks.
But.. it can draw one card ON YOUR TURN, which is helpful since there are those crucial times when you really need to draw a card. Yata Garasu and JoG shares that flaw being both trap cards. Goblin House is bad in early stage, more so because FARM and GRIND deck rely a lot of luck and consistency from the very start of the match. Piper is flexible, and more flexible when drawn with WAND.
I'm not being stubborn. I just don't get why no one ever bothered to try, or simply post Piper as a farm strategy even once. Even in duellinksmeta, or reddit, I have yet to find a Piper in posted decks.
