Doesnt matter
Its just another Simic +1/+1 counter commander, so its not exciting
Like Phyrexian Arena, Lunar Convocation allows you to pay life for cards, and rewards you with a 1/1 flying Bat on each of your turns that you both gain and lose life
Both commanders actually care about lands and help push the theme forward, unlike Lord Windgraces backup options, Gyrus, Waker of CorpsesGyrus, Waker of Corpses or Thantis, the WarweaverThantis, the Warweaver
Commanders like Sythis, Harvest's Hand, Uril, the Miststalker, and Eriette, the Beguiler benefit immensely from all of your bomb auras
This card can single-handedly change the outcome even if the board is stalled: It doesn't need to attack to start burning everyone to death
