I combo Underrealm Lich with Beast Whisper which takes it to a whole new level man youre top decking cards like no other let me see let me pick so many options
Gitrog and Underrealm Lich is a great combo. Gitrog's draw gets replaced by the lich's ability, then when you put a land into your graveyard it will trigger the gitrog's ability again and then the lich's ability will replace the draw until you end up not putting a land card into your graveyard. Also with the lich's ability, you won't draw from an empty library and lose that way. It's pretty neat
Dude, Creakwood Liege is an outstanding Golgari card. +1/+1 for black creatures, +1/+1 for green creatures, and a 3/3 token at the beginning of each of your upkeeps. Phenomenal. I like your list (I would've went in a slightly different order). You hit most of the best in Golgari. That being said, Meren is and always will be, in my opinion, the absolute best Golgari creature ever. Great video. Keep em coming.
Pirate Vraska is the best imo Golgari sacrifice shenanigans can usually finish your opponent after hitting one life quickly anyways and she creates sacrifice fodder for you. Not to mention she's also removal.
Abrupt Decay on 8? And Deathrite Shaman on 7??? Trophy and these two are definitely the top 3. If I am in black and green these 3 Cards are auto Includes 100% of the Time. Gitrog Monster is a way stronger Commander than Meren. Casualties of War is overrated. 6 Mana sorcery speed is rought. Decimate does basicly the same for two mana less except the part of the Planeswalker. And in the Midgame there is a target for every permanent most of the Time. And for Golgari, Windgrace's judgment is the better Card in my opinion. Destroys the best nonland permanent from each opponent at instant speed for 1 Mana less.
