Omnath, Locus of the Roil is a powerful Commander, who can help not only to kill your opponent's creatures when cast, but also puts +1/+1 counters on your creatures, and helps grow your army

If you cast one artifact or Human spell from your graveyard and then have a new Arcade Gannon come under your control in the same turn, you may cast another artifact or Human spell from your graveyard that turn as long as that spell has mana value less than or equal to the number of quest counters on the new Arcade Gannon

If you have a 1st Edition card, look for the stamp on the lower left of the artwork

In addition, the green dot has to be surrounded by a saturated black circle
