Also, if this is such a winning deck, why aren't people bringing this deck to high level tournaments and winning with them?
That's right, because its a flash in the pan, high roll deck. That has hard counters in the best deck in Standard right now. Warrior. If you can't beat warrior, don't bother trying with 'cute' combos.
Tip the Scales forces bad deckbuilding because many of murlocs don't impact the board themselves. But I say if you are having fun, then go for it.
I caution supporting threads like this and encouraging this. People will make the mistake of spending Dust to build this deck and regret it. As a public service, DON'T DO IT! You have to craft 4 Epics that have very little use outside of this deck. You could play the Duel/Lens deck too. But that requires lots of high end Legendary and Epics too or the deck doesn't work.
So my negativity comes in the form of posts like this, getting people to craft cards and decks that are terrible in the long run. This deck will not stay top tier. Build something that actually wins without getting lucky and requiring NO decisions, other than this....
Do I have Lens in my opening Hand? Do I have Tip the Scales in my opening Hand? Get rid of everything not Lens. End of decision making.
