This card is gonna get banned if enough people play it.
Turn 2 win: you have
Stonecoil Serpent
+
Tibalt's Trickery
then use Tibalt's Trickery to counter Stonecoil Serpent.
Turn 3 win: you only have one of the previously mentioned cards AND Wishclaw Talisman. Cast Wishclaw Talisman on turn two, use its ability on turn three to tutor your other combo piece, them boom. You win.
Turn 4 win: you draw Tibalt's Trickery and Valki, God of Lies. Casting Valki then countering him with Tibalt's Trickery.
A FEW NOTES:
ARENA vs Paper Magic: In arena there are handfixing algorithms, meaning you will get the combo more if you have more lands. In paper, you don't have that, so the deck won't be able to work as consistently. basically I'd say aim for 24 lands in paper magic and a lot more in ARENA.
This may not seem very consistent, but its surprising. I haven't tested it too much yet but it seems a lot more consistent than you might think. It's only a two card combo, and we have tutors. Its also cheap, meaning you might get a second chance to pull it off in the same game.
MULLIGANS ARE YOUR FRIEND. If you don't draw your combo, try again. I've won after mulliganing three times. It works.
CARDS YOU SHOULD AIM FOR WITH TIBALT'S TRICKERY. I'm still experimenting and you should too. I like Ugin, Genesis Ultimatum, Emergent Ultimatum, Kiora bests the Sea God, basically anything thats good on the board early.
This deck is nearly the same as the deck in this video, but I've been thinking about this for a lil while and he kinda just made a much better version than mine (but for historic)

(ALSO MONO BLACK MAGIC IS AMAZING CHECK HIM OUT)
(also also I have no idea how to do the lands for this deck... triomes for color fixing to hardcast the big things? locthwain just in case? pathway for color fixing? temple for scrying into combo? Fabled passage to filter deck?)
