You can receive a common (16.7%), uncommon (58.3%), rare (16.3%), or mythic rare (2.6%) card from the main set
Some argue hes even enough of a Game Changer to go on that list alongside Kinnan and Grand Arbiter
I like it in multiple attack brews, aggro, tokens, and alongside Commanders that share combat damage triggers that you already invest in unblockable infrastructure like Whispersilk Cloak
Lost Zone / Kyogre The Kyogre [Celebrations] build of this deck has always intrigued me because you have this wild turn of accelerating Energy to Kyogre with Mirage Gate, emptying out your deck with any card you can, using Energy Recycler [Battle Styles], and flooding your opponents board with damage for the win
accessible to just about everyone
You could also drop a cool $100 for an Earthcraft and unlock one of Magic's easiest 2-card combos
