Aether Revolt: Top Five Green Cards Aether Revolt looks like one of the most powerful sets to be printed in a long, long time, so all this week, Chaz and I will be breaking down the best rares and mythics from the set on a color-by-color basis
Part of this is due to flashback letting you use it twice, and part of it is the political angle for Commander: You can put counters on other players permanents to strike deals or maybe enhance cards like Generous Patron and Nils, Discipline Enforcer
It's also possible to build a Zinnia Commander deck to maximize enter effects, and here's a few cards to help begin that process: Panharmonicon - this four-mana artifact has a static ability that says if a creature or artifact entering would trigger an ability of a permanent controlled by the player, that triggers twice instead
This character lets you be a bit more aggressive in your challenging or get back some of your early-game characters to keep your game going smoothly
I expect Get Lost to play a role here as well, especially for control decks to cleanly answer opposing copies of The Wandering Emperor
