More of this please!
If only all of us who first hopped aboard the bandwagon during the late '90s had known that at the time
With The First Chapter, Rise of the Floodborn, Into the Inklands, and Ursula's Return out of the picture, several cards that were staples in the game that didn't receive a reprint are no longer viable unless you're playing in the Infinity format

Blackmail Target player reveals three cards from their hand and you choose one of them for that player to discard Duress Target opponent reveals their hand and you choose a noncreature, nonland card for that player to discard Encroach Target player reveals their hand and you choose a nonbasic land card for that player to discard (can hit non-basic lands!!) Grief A 3/2 creature with Evoke (Evoke cost is exile a black card from your hand) When it enters the battlefield, target opponent reveals their hand and you choose a nonland card for that player to discard Inquisition of Kozilek Target player reveals their hand and you choose a nonland card from it with mana value 3 or less for that player to discard Mires Toll Target player reveals a number of cards from their hand equal to the number of Swamps you control and you choose one of them for that player to discard Thoughtseize Target player reveals their hand and you choose a nonland card for that player to discard you lose 2 life Unmask Exile a black card from your hand rather than pay this spells mana cost Target player reveals their hand and you choose a nonland card for that player to discard There are tons and tons of Black discard effects in MTG

Brook , when played or attacking, can reduce the cost of an opponents character by -1 and KO a 0-cost character
Its a hard life reviewing Magic cards, but I will do What Must Be Done
