gives you a green blue deck with tons of landfall and manifest cards, rewarding you for doing the most boring action in Magic, playing lands, by turning them into manifest dread triggers off of Zimone, Mystery Unraveler or turning a facedown card right side up if you play two lands in a turn
Void is a riff on leaves the battlefield triggers that adds warp to count for the already-easy-to-use mechanic
(It loses its other colors and creature types.) If a player is instructed to put a card into their graveyard from their library without using the word "mill," (by the effect of Rowan's Grim Search from Wilds of Eldraine , for example), that card isn't a legal target for The Master's last ability

if I was ranking these for Constructed or Cube instead of Commander, itd likely take the top slot
At the end of your turn, you can use one of your Active Pokmon's attacks
