Until Innistrad Remastered, Edgar Markov was very hard to get hold of
Myrkul, Lord of Bones (Check it out here) was built as the leader of a Midrange and Constellation deck that ran a bunch of dorks with ETB abilities for value (like Liliana's Specter and Archon of Cruelty), sacrificed them for value (High Market and Dockside Chef), netted a return as an enchantment to trigger another ETB for it and constellation dorks (like Underworld Coinsmith and Eidolon of Blossoms) and then added in some ramp, answers, card flow, and called it a deck
Ive found that for things are pretty good the main accessory items like deck boxes, sleeves, and playmats
Goldeens horn attack on turn 1 did 10 damage and Seakings waterfall on turn 2 did 30 damage
The messaging is clear: RG wants to play overstatted monsters (Grumgully makes everything into an overstatted monster) and overwhelm the opponent with powerful midrange threats (which RG usually does)
