After testing the spellstones for quite a while i can safely proclaim that.. They suck dick.

This iteration is very strong vs Raza priest and Jade Druid, while being decent vs cubelock and tempo decks. Struggles vs aggro (paladin almost an auto loss).

Counterfeit Coin instead of a second backstab makes it even worse against aggro, but allows you to combo the Minstrel more reliably. Your mulligan needs to be draw. This deck is insanely dependant on drawing crucial cards dependant on the matchup, be it Saps, Oracles or weapon buffs.

This particular amount of pirates makes it remain strong even vs a turn 6 Geist. This amount of weapon buffs makes it matter less whether the pirate buffs hit or not. But you can always adjust it to your micro-meta

There are two Leeching Poison cards to increase the odds of drawing one. You can switch it out for extra draw instead. That last point shows the beauty of rogue in particular. You can swap any of these cards for more draw.

Mulligan?

Now, here's a small problem : it all depends on what the rest of the hand is. Got a shinyfinder? Keep a deadly poison. Got both of those? Keep a leeching as well! No Shinyfinder? Toss both poisons out. Are you on coin, or have a 0-cost spell? Keep Minstrel. Got neither of these cards? Keep a coldlight oracle. What about having kingsbane AND shinyfinder? Only keep the weapon with finder if you have a poison on top of it. Only keep pirates if you are on coin with a plethora of weapon-related cards already in hand.... The list goes on unfortunately.

You'll get a hang of it eventually, or you won't and instead will move to cubelock. Whichever the case, good luck and try to have fun.
