For two mana, this lets you Regenerate the enchanted creature for three red mana at a time
With Obosh in play, Sulfuric Vortex is suddenly dealing 4 damage to each player, while cards like Underworld Dreams and Syr Konrad, the Grim are dealing 2 damage with each trigger
Graveyard decks in particular create an engrossing standoff, since it can be terrifying to risk accidentally accelerating your opponents plan but if you have at least some tech to target the yard, you can also force them to keep their own sequencing a lot tighter than they might be used to
Furthermore, its attack does nearly unlimited damage because players can discard any amount of energy to deal 50 damage for each energy discarded from their hand
This strategy works sort of similarly to the next deck Im going to mention because it doesnt get too much going in the first three or four turns
We are only getting two Commander decks for this release
